Is chloroplast eukaryotic or prokaryotic?
Answer:
Chloroplasts are eukaryotic, as they are present in all eukaryotic cells and all prokaryotic cells lack chloroplasts
Explanation:
Approximately 20% of the world’s adult population are able to digest milk sugar (lactose).They are “lactose tolerant.” This trait is known to be controlled by a single dominant gene. Therefore, we would expect that
no lactose tolerant individuals have two biological parents that are lactose INtolerant.
all lactose tolerant individuals to be heterozygous for the gene.
60% of lactose INtolerant individuals would be heterozygous.
all children of lactose tolerant parents will also be lactose tolerant.
Answer:
No lactose individuals have two biological parents that are lactose intolerant
Explanation:
In this case lactose intolerance would be coded for a recessive gene (r). if both parents are lactose intolerant the would both be the genotype (rr) . For individual to be lactose intolerant atleast one parent most be lactose tolerant posesing the dominant (R) gene. Which both parents in this example lack.

How many subunits are in ribosomes??
Answer:
2 subunits
Explanation:
Arrange these components of the mammalian immune system as it first responds to a pathogen in the correct sequence. I. Pathogen is destroyed and digested and parts are presented. II. Lymphocytes secrete antibodies. III. Antigens from pathogens bind to matching receptors on lymphocytes. IV. Lymphocytes specific to a pathogen's antigens become numerous. V. Only memory cells remain.
Answer:
The correct sequence is:III) Antigenic determinants from pathogen bind to antigen receptors on lymphocytes.
IV) Lymphocytes specific to antigenic determinants from pathogen become numerous.
II) Lymphocytes secrete antibodies.
I) Pathogen is destroyed.
V) Only memory cells remain.
Explanation:
Effective resistance against infection is essential for the development and functioning of the mammalian organism, and for it to be effective, multiple defense systems must be available. In order to meet these objectives, the body has developed a complex system of overlapping and interrelated defense mechanisms, which together can destroy or control almost all invaders.III) Antigenic determinants from pathogen bind to antigen receptors on lymphocytes. It consists of the binding of the foreign antigen to the specific receptors existing on the membrane of mature lymphocytes. The B lymphocytes that mediate humoral immunity express antibody molecules on their surface, which bind to foreign proteins, polysaccharides or lipids in their soluble form; T lymphocytes, responsible for cellular immunity, express so-called T cell receptors (TCR), which recognize small sequences of antigenic peptides.
IV) Lymphocytes specific to antigenic determinants from pathogen become numerous.II) Lymphocytes secrete antibodies.
Activation phase: sequence of events that occur in lymphocytes as a result of specific antigen recognition. All lymphocytes undergo two fundamental changes: a) proliferation: expansion of antigen-specific clones and amplification of the protective response, in which the CD4 T lymphocyte, capable of activating CD8 B and T lymphocytes, assumes a preponderant role; b) differentiation: stage in which effector cells and memory cells are formed. The first produce various substances that can interact with the antigen, such as antibodies and lymphokines; the second are partially differentiated lymphocytes, that is, they do not become effector cells.
I) Pathogen is destroyed.
In this phase, the T lymphocytes differentiated into effector cells migrate to the sites of attack, where they carry out their functions of eliminating pathogens, while the B lymphocytes perform them in the peripheral organs themselves.
V) Only memory cells remain.
One of the most important consequences of the adaptive immune response is the establishment of the state of immunological memory, which lies in the ability of the immune system to respond more quickly and efficiently to microorganisms that have previously infected the host and it reflects the preexistence of a clonally expanded population of antigen-specific lymphocytes. We call, therefore, the immune response that the organism gives when it comes into contact for the first time with a foreign agent and from which a series of events derives that include nonspecific innate defense mechanisms and adaptive response mechanisms, if the pathogen manages to survive the first ones.
when does a star start to die
Answer:
Several billion years after its life starts, a star will die. How the star dies, however, depends on what type of star it is. Stars Like the Sun. When the core runs out of hydrogen fuel, it will contract under the weight of gravity. However, some hydrogen fusion will occur in the upper layers. As the core contracts, it heats up.

Its about bio and its confusing
Answer:
a) the process of mitosis generates new cells that are genetically identical to each other. mitosis helps organisms grow in size and repair damaged tissue. some species of alge are capable of growing very quickly.
b) more growth occurs in the root tips and very little new cell development occurs in woody stems after they are formed
c) sequential order means put things in order.
A B C D E
Hello again, Bakere!
a) Mitosis, the dividing of a single cell into two daughter cells, is a way for the plant to stay healthy-looking and strong. All cells die eventually, and they must be replaced by new, fresh ones. This replacement occurs through mitosis. Mitosis also allows the plant to grow, as mitosis is found more frequently in growing areas than ones that are finished growing. Since mitosis makes more cells, you will find much more mitosis occurring in a new shoot than in an old tree, because the old tree doesn't need a bunch of new cells to continue growing.
b) Mitosis is more frequent on the outside of the root because new cells are needed constantly as multitudes of them are scrubbed away by rough dirt. On the inside of the root, however, there is little to no exposure to harsh soil erosion. Because of this, mitosis is needed less here - only to replace the dying cells.
c) The order for the letters should be: A, E, D, B, C. I'm including a picture to help you understand why. :)

which 3 beak types will most likely be present in surviving species
based of these are true
A. Metal is denser than milk
B. Air and water are equal dense
C. Rain Water is less dense than fog
D. Orange Juice is denser than a whole orange
Answer:
A.
Explanation:
because solid metals will sink when placed on top of whole milk.
Metal is denser than milk is the property of density, these are true. Thus option A is correct.
What is density ?The density can be defined as its mass per volume and it is the ratio between mass and volume, where how much stuff of an object has in a unit volume.
Density is a calculation of matter, where it shows how tightly matter is mixed together, density was discovered by the Greek scientist Archimedes
The density of an object can be represented as the mass (m) can be divided by the volume (v)
Density = Mass/Volume
The SI unit of density is represented as kilogram per cubic meter (kg/m3) or in cgs unit it can be represented as grams per cubic centimeter (g/cm3).
Thus option A is correct.

a. If you were designing a pigment to maximize light capture in a new kind of solar array what light absorbing properties would have?
b. what molecule in the sumary equation for photosynthesis ends up in the sugars made by photosynthesis?
c. When Jasmine was a baby, her parents planted a jasmine plant weighing 1 kg in a container in their yard with 50 kg of soil. When Jasmine was 18, the plant was estimated to weigh 75 kg. Then it was time to transplant the plant into the family yard so it could continue growing. When the soil in the container was weighed, its mass was 50 kg. Over the years Jasmine's parents neither added nor removed soil from the container with the plant in it. How did the plant increase in mass by 74 kg while the soil did not change in mass and never needed adding to over the years?
Answer:
Following are the solution to the given points:
Explanation:
In point a:
When a light absorption dye was to be introduced to optimize the plant's absorbing capacity, the paint could absorb wide different wavelengths besides the observable light spectrum. It must also absorb the UV only at IR light rate to maximize the fluorescence intensity.
In point b:
Its molecule in the production of pentose sugar is the nitrogen and hydrogen atoms of carbon dioxide and water ions of air. Its water oxygen atoms are emitted through oxygen atoms during this phase.
In point c:
Its plant increased with weight while decreasing the weight of the earth, so because manufactured goods needed for plant growth are carbon dioxide from water and air, provided to a plant every day and nitrogen extracted from of the atmosphere through means of microbial materials into nitrogen. So, even if the plant raised its weight, the soil does not change the weight.

.In the cladogram above, which pair of species is most closely related to each other? * 2 points a. Hamster and salamander b. Lizard and salamander c. Salamander and mountain lion
Answer:
b. Lizard and salamander
Explanation:
Both Lizard and salamander are closely related species because of their body structure and appearance. Both Lizard and salamander have similar shape and structure but belongs to different group. Lizard belongs to reptiles whereas salamander belongs to amphibian family. Both Lizard and salamander are vertebrates, cold blooded animals, carnivorous, has a tail and four legs. So we can conclude that both Lizard and salamander are closely related to each other.
Identify the kind of response to the following argument: Argument: In nature, a species is more likely to survive when its weak members die out, so we should let the weak in our society die out. Response: In nature, a species is more likely to survive when it lives in its natural habitat, so we should live in our natural habitat. A. refutation by parallel reasoning B. refutation by reduction to absurdity C. refutation by counterexample D. not a refutation
Answer:
A. refutation by parallel reasoning
Explanation:
A refutation by parallel reasoning is an analogical inference between two arguments. This type of refutation occurs when an argument is invalidated by showing that the argument's conclusion is not supported by its premises, thereby the structure of the argument is incorrect. The parallel argument should demonstrate that the premises of the target argument are founded in a fallacy or don't provide a strong enough rationale to support/accept its conclusion.
Can someone please help me answer this question? Thank you.
Answer:
The correct answer is -
C is parent cell
A is under meiosis
B is a sex cell
Explanation:
In the given question, the diagram shows three different cells in which the cell C is the parent cell that is about to undergo meiosis that can be identified by the quantity or numbers of chromosomes present in the cell which is highest among all.
The cell that is already in the meiosis is cell A, it is the cell that is produced after meiosis 1 in the meiosis cell division as it has half number of chromosomes to parent cells.
The sex cell or gamete is cell C that has a haploid number of chromosomes which makes this process reduction division
A significant shift in the environmental conditions over a very short period of time caused most groups of dinosaurs to become extinct because of their inability to adapt fast enough. This allowed for a variety of niches to open providing current organisms new opportunities.

Which of the following is a term that most correctly describes this process?
A. Adaptive radiation
B. Gradualism
C. Convergent evolution
D. Genetic drift
Answer:
A. Adaptive radiation
Explanation:
Which condition had the greatest impact on the emergence of new species in Earth's history?

Cory states the following argument about the evolution of aardvarks and anteaters.
"Aardvarks and anteaters both use long, sticky tongues to capture and eat ants or termites. Aardvarks are native to Africa, while anteaters are native to the Americas. However, their similarities provide evidence that both groups of species evolved from a common ancestor that used its tongue to eat ant-like insects."
Which claim, if supported by evidence, would provide the strongest counter-argument AGAINST Cory's argument?
A. The tongues and diet of aardvarks and anteaters are an example of convergent evolution.
B. The tongues and diet of aardvarks and anteaters are an example of adaptive radiation.
C. The Americas and Africa were once joined together, and animals roamed freely between the two lands.
D. A long, sticky tongue evolved in response to the tunneling behavior of ants, an example of coevolution.
