When we burn oil, coal, and gas, we change the ocean's basic chemistry, making it more acidic. Our seas absorb as much as a quarter of all man-made carbon emissions. Since the start of the Industrial Revolution (and our coal-burning ways), the ocean has become 30 percent more

Answer:

A - Burning coal

Explanation: When you burn coal you create polution which contributes to global warming, and global warming warms up the earth.

Compare the reproduction in Hydra and Amoeba?​

Answers

Answer:

Hydra:

Reproduction by budding in Hydra.

Amoeba:

Reproduction by binary fission in Amoeba.

Hydra:

Budding means sexual reproduction in which a new organism develops from a bud in the parent.

Amoeba:

Binary fission is the type of asexual reproduction in which the parent divides to give rise to two daughter organisms.

Hydra:

In budding process, bud is simply an outgrowth of cells at one particular site.

Amoeba:

The parent replicates its genetic material and divides it equally between the two daughters in binary fission.

Hydra:

The bud or the newly formed organism remains attached to its parent until maturation.

Amoeba:

Both the cytoplasm and the nucleus of the parent divides into two.

Name two types of lateral pathways for the movement of sucrose from source cell into the sieve tube

Answers

Answer:

Diffusion and active transport.

Explanation:

Diffusion and active transport are the two types of lateral pathways that is responsible for the movement of sucrose from source cell into the sieve tube. Sugar molecules are moved into the sieve elements which are the phloem cells through active transport i.e. with the use of energy. The water produces turgor pressure in the sieve elements, which pushes the sugars and fluids down the phloem tubes toward the storage sites. it also moved through simple diffusion due to difference in concentration i.e. from higher to lower concentration region.

Why is a sea otter a “keystone”??

Answers

Explanation:

Sea otters are an iconic species, representing the beauty and diversity of marine life found along California’s coastline. They’re also considered a keystone species because of their critical importance to the health and stability of the nearshore marine ecosystem. They eat sea urchins and other invertebrates that graze on giant kelp.

This is because eliminating them would cause a trophies cascade. The sea otter’s prey would increase, and the prey of that prey would decrease. Thus, otters are a “keystone” species.

Explain the relationship between mutations, adaptations,
natural selection, and extinction.

Answers

Answer: A mutation results in different alleles for a gene and these different alleles will cause adaptations that may be favorable or unfavorable. If no species in an area has adaptations suited for the environment after it changes, extinction will occur.Adaptations result from random mutations in the genes of organisms. Depending on the environment, these adaptations may be favorable or unfavorable. If an adaptation is favorable, it is selected by nature and, over time, more and more organisms in a population will have it. If the environment changes so much that the adaptations of a species are no longer enough for the species to survive, extinction will occur.Mutations is very different because it results in different alleles for a gene.Adaptations is where an animals ADAPTS to an environment.Natural selection consists of overproduction,variation, favorable adaptations.extinction is when a species completely disintegrates.

1. Which of the following events is not a source of genetic variation in eukaryotic organisms?

J. Mutation
K. Independent assortment
L. Mitosis
M. Fertilisation

Answers

Answer:

Mitosis

Explanation:

Mitosis is not a source of genetic mutation because it take place mostly in the somatic cells. This is because it does not lead to the production of gametes . In mitosis, the parent cells divide into two daughter cells and each daughter cells are genetically identical to the parent cell because they carry the same number of chromosomes as the parent cell. There is no genetic variation in this.

Many scientists say that there is a good reason for gaps in the fossil record. Can you explain why some extinct animals and plants were never fossilized?

Answers

Answer:

For an organism to become a fossil, it must not decompose or be eaten. This can happen if the organism either lives within or is moved to a place where it can be buried and kept from decaying. When an organism is buried quickly, there is less decay and the better the chance for it to be preserved.

In general, do organisms that have more traits in common also share more genes?

Answers

Answer:

In general, organisms that share similar physical features and genomes tend to be more closely related than those that do not. Such features that overlap both morphologically (in form) and genetically are referred to as homologous structures; they stem from developmental similarities that are based on evolution.

what is cell and its function​

Answers

Cells are the basic building blocks of all living things.

They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.

[tex]\sf\huge\underline\purple{Cell:-}[/tex]

Definition:-

“A cell is defined as the smallest, basic unit of life that is responsible for all of life’s processes.”

[tex]\rightarrow[/tex] Cells are the structural, functional, and biological units of all living beings. A cell can replicate itself independently. Hence, they are known as the building blocks of life.

[tex]\rightarrow[/tex]Each cell contains a fluid called the cytoplasm, which is enclosed by a membrane. Also present in the cytoplasm are several biomolecules like proteins, nucleic acids and lipids.

[tex]\sf\large\underline\purple{Functions:-}[/tex]

Following are the various essential functions of cells:

Cells provide structure and support to the body of an organism.The cell interior is organised into different individual organelles surrounded by a separate membrane.The nucleus (major organelle) holds genetic information necessary for reproduction and cell growth.Every cell has one nucleus and membrane-bound organelles in the cytoplasm.Mitochondria, a double membrane-bound organelle is mainly responsible for the energy transactions vital for the survival of the cell.Lysosomes digest unwanted materials in the cell.

Which of these is a difference between DNA and RNA?
DNA is found in the nucleus; RNA is never found in the nucleus.
DNA consists of five different nucleotides; RNA consists of four different nucleotides.
RNA is double-stranded; DNA is single-stranded.
DNA contains thymine; RNA contains uracil.
In DNA, adenine pairs with guanine; in RNA, adenine pairs with thymine.

Answers

Like DNA, RNA is made up of nucleotides. There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.

Neither anticipated that the cause of the conflict might cease with or even before the conflict itself should cease. Each looked for an easier triumph, and a result less fundamental and astounding. Both read the same Bible and pray to the same God, and each invokes His aid against the other. It may seem strange that any men should dare to ask a just God's assistance in wringing their bread from the sweat of other men's faces, but let us judge not, that we be not judged. The prayers of both could not be answered. That of neither has been answered fully. The Almighty has His own purposes. "Woe unto the world because of offenses; for it must needs be that offenses come, but woe to that man by whom the offense cometh." If we shall suppose that American slavery is one of those offenses which, in the providence of God, must needs come, but which, having continued through His appointed time, He now wills to remove, and that He gives to both North and South this terrible war as the woe due to those by whom the offense came, shall we discern therein any departure from those divine attributes which the believers in a living God always ascribe to Him? Fondly do we hope, fervently do we pray, that this mighty scourge of war may speedily pass away. Yet, if God wills that it continue until all the wealth piled by the bondsman's two hundred and fifty years of unrequited toil shall be sunk, and until every drop of blood drawn with the lash shall be paid by another drawn with the sword, as was said three thousand years ago, so still it must be said "the judgments of the Lord are true and righteous altogether."
