certain oceanic living organisms obtain the
energy needed to survive?
A. from the rain
B. from chemical energy associated with deep-ocean thermal
vents
C. from wind
D. from the temperature of the air

Answers

Answer 1

Instead of the sun's energy, certain organisms living in the ocean can obtain their energy from the chemical energy associated with deep-ocean thermal vents. Option B.

Alternate form of energy for living organisms

All organisms need energy in order to survive and most organisms obtain their energy directly or indirectly from the sun.

Some organisms are able to obtain their energy directly by fixing carbon dioxide into carbohydrates using the energy from the sun. This process is known as photosynthesis and such organisms are known as producers.

Other organisms, that are not able to directly utilize the energy from the sun rely on the energy fixed by producers. They consume producers and extract their own energy from them. Such organisms are known as consumers.

Instead of the energy from the sun, some organisms are able to make use of the energy locked up in certain chemicals to make carbohydrates. Such chemicals can be found in association with hydrothermal vents deep in oceans. Such organisms carry out chemosynthesis instead of photosynthesis.

T/F: Kelps with air bladders are common along the western and northwestern Pacific coasts of the United States

Answers

Kelps with air bladders are common along the western and northwestern Pacific coasts of the United States it is a true statement

The primary moisture-bearing and rain-producing air mass throughout the year is the maritime Tropical (mT). It moves toward the pole in the winter and is cooled by the earth's surface. As a result, it has low stratus or stratocumulus clouds, drizzle, and poor visibility.

Due to the high-pressure areas that are prominent there, warm, humid maritime tropical (mT) air develops over tropical and subtropical ocean waters. On the other hand, just south and east of the substantial winter oceanic low-pressure regions, cool, moist maritime polar (mP) air develops over the colder subpolar ocean waters.

Humans have long been concerned with forecasting and predicting future weather conditions as a result of the variability of weather phenomena.

Meiotic drive is a phenomenon observed occasionally in which a heterozygous genotype does not produce a 1: 1 proportion of functional gametes, usually because one of the gametic types is not formed or fails to function. Suppose that an allele D shows meiotic drive such that heterozygous Dd genotypes form 3/4 D-bearing and 1/4 d-bearing functional gametes. What is the expected ratio of genotypes in the F2 generation of a monohybrid cross under the assumptions stipulated below? (Hint: Use Punnett squares.)

(a) The meiotic drive occurs equally in both sexes.

(b) The meiotic drive occurs only in females.

Answers

Answer:

Explanation:

To find the expected ratio of genotypes in the F2 generation of a monohybrid cross, you can use Punnett squares.

(a) If the meiotic drive occurs equally in both sexes, you can represent the cross as follows:

F1 generation:

DD x Dd

F2 generation:

DD Dd dd

DD Dd dd

In this case, the expected ratio of genotypes in the F2 generation is 1:2:1, which means that there is a 1/4 chance of producing a DD genotype, a 1/2 chance of producing a Dd genotype, and a 1/4 chance of producing a dd genotype.

(b) If the meiotic drive occurs only in females, you can represent the cross as follows:

F1 generation:

DD x dd

F2 generation:

DD Dd dd

DD Dd dd

In this case, the expected ratio of genotypes in the F2 generation is 3:1, which means that there is a 3/4 chance of producing a DD or Dd genotype and a 1/4 chance of producing a dd genotype.

Answers

Weathering. Decomposers are critical in the nitrogen and phosphorus cycles because they are responsible for the fixation of the nutrients into a bioavailable form.

Since the main source of phosphorus is found in rocks, the first step of the phosphorus cycle involves the extraction of phosphorus from the rocks by weathering. Weather events, such as rain and other sources of erosion, result in phosphorus being washed into the soil.Effective population size (Ne) is one of the most important parameter in population genetics and conservation biology. It translates census sizes of a real population into the size of an idealized population showing the same rate of loss of genetic diversity as the real population under study.Ne is defined as the size of an ideal Wright–Fisher population exhibiting the same amount of genetic drift and inbreeding as the population under consideration (Wright, 1931).

Answers

Answer A is the right choice. A specific tRNA molecule's anticodon complements the corresponding mRNA codon.

The mRNA molecule's matching codon and the anticodon of the tRNA are complementary. As a result, complementary base pairing allows the tRNA to bind to the mRNA codon. The appropriate mRNA codon and the tRNA anticodon are hence complementary. A trinucleotide sequence called an anticodon is found at one end of a transfer RNA (tRNA) molecule and is complementary to a corresponding codon in an mRNA sequence.

The tRNA molecules are in charge of pairing amino acids with the proper codons in the mRNA. Each tRNA molecule has two separate ends; one of them attaches to a particular amino acid, while the other one binds to the appropriate mRNA codon.

Cell cycle regulation: proteins• Cell cycle is controlled by cyclins and cyclin-dependent kinases (CDKs)- cyclin and CDKs are specific to each checkpoint in each organism- stop progression if things aren't going right- stop cycle at each check point until cyclin/CDK allow progression

Answers

The correct answer is  Any process that controls the series of events by which a cell goes through the cell cycle is known as Cell cycle regulation.

By phosphorylating the target genes, such as the tumour suppressor protein retinoblastoma, the synthesis of cyclin/CDKs regulates the course of the cell cycle (Rb). The activation of cell-cycle checkpoints in response to DNA damage inhibits the activation of cyclins/CDKs, which is activated by mitogenic signals [8]. Protein kinases called cyclin-dependent kinases (CDKs) depend on a distinct subunit, the cyclin, which supplies the domains necessary for enzymatic activity. In response to various extracellular and intracellular signals, CDKs modify transcription and play significant roles in the regulation of cell division. The groups of protein kinases known as cyclin-dependent kinases (CDKs) were initially identified for their function in controlling the cell cycle. Additionally, they control mRNA processing, transcription, and nerve cell differentiation.

______are used by the body as catalysts and lenzymes.
Minerals
Fats
Carbohydrates
Vitmains

Answers

Vitamins are used by the body as catalysts and enzymes. The correct option is D.

What are vitamins?

Vitamins are organic substances that are generally classified as either fat soluble or water soluble. Fat-soluble vitamins dissolve in fat and build up in the body.

Except for vitamin C, all water-soluble vitamins have a catalytic function, which means they act as coenzymes of enzymes involved in energy transfer or the metabolism of fats, carbohydrates, and proteins.

Catalysts are substances that change the rate of a chemical reaction while remaining unchanged. Enzymes are proteins that speed up chemical reactions by converting the substrate into the product.

Thus, the correct option is D.
