Describe the
functions of the cell membrane
and cell wall
Answer:
cell membrane: provides protection for a cell . It also provides a fix environment inside the cell and the membrane has several different fonctions . One is to transport nutrients into the cell and also transports toxic substance out of the cell.
cell wall: cell wall is a structual layer sorrounding some types of cells , just outside the cell membrane . it can be tough , flexible ,and sometimes riding. it provides the cell with both structual support and protection , and also acts as a filtering machine.
Eutrophication both hurts and helps
aquatic environments.
true
false
Answer:
False. Eutrophication is an enrichment of water by nutrient salts that causes structural changes to the ecosystem such as: increased production of algae and aquatic plants, depletion of fish species, general deterioration of water quality and other effects that reduce and preclude use”.
The table below Anton Leeuwenhoek devised a primitive microscope to observe a sample of his tooth scrapings. How did this help contribute to cell theory?
It helped to show that cells cannot function independently.
It helped to show that some bacteria can swim like fish.
It helped to show that some bacteria are just one cell.
It helped to show that cells can be created from thin air. shows the average wind speeds of four hurricanes in Florida.
Answer:
The correct answer is - option C.
Explanation:
Anton Leeuwenhoek observed the presence of organisms in his tooth scratch or scrapings under the primitive microscope made by himself. At that time there was no knowledge about the bacteria and he named these small creatures as animalcules. These animalcules were bacteria actually.
These creatures were single-cell organisms and able to perform the function as an entity and postulate that bacteria is a single which is a fundamental unit of function and structure of all living organisms.

in the blank circle, draw the moon phases we would see if we were on Earth in the diagram and then write the name of that moon phase on the blank line
Answer:yThe Moon has phases because it orbits Earth, which causes the portion we see illuminated to change. The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days. ... As the Sun sets, the Moon rises with the side that faces Earth fully exposed to sunlight (5).

All organisms must regulate_____ by turning genes on and off different cells at different times. In prokaryotic cells, related genes may be organized into_____, which can be turned on and off as a single unit. Eukaryotes have more complex modes of control, including the packing of chromosomes,____(which can produces several mRNAs from a single gene), and the control of translation. An understanding of gene regulation mechanisms has led to several interesting and important applications. For example, the loss of gene regulation can result in cancer, or out-of-control cell growth. And___can produce new live individuals, while___can produce potentially therapeutic stem cells.
Answer:
All organisms must regulate gene expression by turning genes on and off different cells at different times. In prokaryotic cells, related genes may be organized into operons , which can be turned on and off as a single unit. Eukaryotes have more complex modes of control, including the packing of chromosomes, RNA slicing (which can produces several mRNAs from a single gene), and the control of translation.
An understanding of gene regulation mechanisms has led to several interesting and important applications. For example, the loss of gene regulation can result in cancer, or out-of-control cell growth. And reproductive cloning can produce new live individuals, while therapeutic cloning can produce potentially therapeutic stem cells.

Is the kingdom monera prokaryotic or eukaryotic
they are prokaryotic
Explanation:
the kingdom monera is under the bacteria family so it has no membrane bound organelles
The kingdom monera is prokaryotic. Monera is a kingdom of organisms which lack a defined nucleus of organelles, nor do any of them show multi-cellular body designs.
Determine if it's Asexual or Sexual: The DNA of a bacterium doubles. The cell divides in half in a process called fission. This process continues every 20 minutes until food for the bacteria becomes scarce. The population levels off.

Hope That help
A population of birds eats nuts and seeds. Some birds have larger beaks, and some have smaller beaks. A pair of birds usually produces four or five offspring each year. After several yeaers of little rain, the seeds became larger and larger. The birds with larger beaks were better at cracking these seeds. After several generations, the average beak size in the population increased. Bird beak size increasing after several generations is: a. decent with modification. b. variation. c. overproduction. d. adaptation
As far as I can tell, the answer would be D. Adaptation. The birds are evolving to adapt to their environment, and as such, their beaks are getting larger to crack larger seeds.

Why does a pea plant with the genotype Rr have round seeds, not wrinkled ones.
Answer:
Wrinkled peas need to have genotype rr, since the wrinkled trait (r) is recessive

discuss the contributions of pasteur, and koch to 'germ theory of disease' and to the prevention of diseases
Answer:
Pasteur showed that putrefaction is a process associated with organisms present in the air, while Koch identified the germs that cause different diseases
Explanation:
The germ theory states that pathogenic microorganisms called germs cause the disease state observed in a particular (infected) organism. The term 'germ' includes pathogenic bacteria, protists, fungi, and even non-living pathogens (e.g., viruses). This theory was developed and accepted due to the work of Louis Pasteur and Robert Koch. In the 1860s, Pasteur showed that germs were omnipresent in a flask open to the air, showing that putrefaction and fermentation are caused by these microorganisms. Moreover, in the 1880s, Koch identified the germs that cause different diseases, including tuberculosis (Mycobacterium tuberculosis) and cholera (Vibrio cholerae).
What describes gneiss?
Gneiss is a high grade metamorphic rock, meaning that it has been subjected to higher temperatures and pressures than schist. It is formed by the metamorphosis of granite, or sedimentary rock. Gneiss displays distinct foliation, representing alternating layers composed of different minerals.
Gneiss is a type of metamorphic rock that is formed by high pressure and temperature caused by the earth's surface.
What are metamorphic rocks?Metamorphic rocks are those rocks that are formed when other rocks are introduced under high temperatures and pressure that is exerted by the layers of the earth. There are three types of metamorphic rocks.
Since gneiss is a high-grade metamorphic rock, it has undergone more intense heat and pressure than schist. It is created through the transformation of sedimentary rock, such as granite.
Gneiss has distinctive foliation or alternate layers made of various minerals. This rock comes under the metamorphic regional type of rock.
Therefore, Gneiss rocks are those metamorphic rocks that are formed on convergent plate boundaries.

Which diagram represents binary fission?
Answer:
Diagram A
Explanation:
This is because binary fission is asexual reproduction by a separation of the body into two new bodies. In the process of binary fission, an organism duplicates its genetic material, or deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA.

In chemical weathering, the composition of the weathered substance is changed.
C.
In physical weathering, the composition of the weather substance is changed.
D.
Chemical weathering is always faster than physical weathering.
Answer:B. In chemical weathering, the composition of the weathered substance is changed.
Explanation: Chemical weathering is the act of changing its form, such as color. Physical weathering remains in its shape, but can change due to breaking into smaller sediments.

suggest two other features in which the sugarcane flower might different from insect pollinated flower
Answer:
Explanation:
Sugar cane is wind pollinated so the pollen is light weight, non-sticky, flowers producing pollen and ovules are extended above the plant so the pollen can be easily picked up by the wind and filtered out of the wind by the stigmas of the "female."
