Answer:

No population can grow infinitely.

Explanation:

There's only a finite amount of resources in an ecosystem. The habitat always has some sort of limit depending on how many resources it has.

gladu [14]

A particular plant has two alleles that control the length of its stem. T represents the dominant allele that codes for a tall stem, and t represents the recessive allele that codes for a short stem. Based on the Punnett squares, which two statements are true about the genotype of the plant’s stem length?

First Generation

__t_ t

T Tt Tt

Second Generation

__T_ t

T TT Tt

t Tt tt

Select all the correct answers.

A) Plants with short stems are homozygous for that trait.

B) Plants with tall stems are always homozygous for that trait.

C) Both parent plants in the second generation are heterozygous.

D) Both parent plants in the second generation are homozygous.

The correct answers are options A and C.

<h3 /><h3>How, explain your answer briefly?</h3>

The Statement A says that the plants, which have a short stem is homozygous for the trait. According to the question, the allele for the short height is recessive. A recessive trait can only be observed, when the dominant allele is not at all present. Hence, the plant must have tt allele, so, the plant having short stem would be homozygous recessive.

The statement C says that the both parents in second generation are heterozygotes. It is given that the parents in the second generation have aa genotype Tt. In this case, both the alleles are different, hence, the parent plants are heterozygotes.

Thus, this could be the answer.

The _________ of an organism is defined as all the chemical processes that occur in the cells of that organism. O

Neporo4naja [7]

Answer:

The correct answer is d. Metabolism

Explanation:

Metabolism is a series of chemical reactions that are interconnected with each other. Metabolites are the compounds that are involved in a metabolism process. Metabolism consists of all the chemical process that occurs in a cell of the body of an organism.

Metabolism consists of two pathways, anabolic pathway, and catabolic pathway. In anabolic pathway synthesis of a larger molecule occurs from smaller molecules like the formation of glucose from CO₂ and H₂O during photosynthesis.

In catabolism, oxidative breakdown of these large molecules into smaller molecules takes place like conversion of glucose into CO₂ and H₂O during respiration.

Therefore the metabolism of an organism is defined as all the chemical processes that occur in the cells of that organism.

Cytochalasins bind actin and block actin microfilament assembly. Cells treated with cytochalasins will not divide. How do cytoch

natali 33 [55]

Answer:

The correct answer will be-cytochalasin act by blocking the polymerization of actin filaments.

Explanation:

Cytochalasins are the metabolite product obtained from the fungus which has can bind the actin filament and block the polymerization of actin.

Cytochalasins bind the barbed end of the microtubule which represents the plus of the microtubule, it then blocks the assembly and disassembly of the actin filaments and thus blocks the cell division.

The cytochalasins are used by the researchers to study the process which takes place during the cell division.

Thus, cytochalasin act by blocking the polymerization of actin filaments.

Cytochalasins are fungal metabolites that have the ability to bind to actin filaments and block polymerization and the elongation of actin

As a result of the inhibition of actin polymerization, cytochalasins can change cellular morphology, inhibit cellular processes such as cell division, and even cause cells to undergo apoptosis.

Cytochalasins are known to bind to the barbed, fast growing plus ends of microfilaments, which then blocks both the assembly and disassembly of individual actin monomers from the bound end

The use of cytochalasins has allowed researchers to better understand actin polymerization, cell motility, ruffling, cell division, contraction, and cell stiffness.

What causes the weather conditions using what we learned.

miv72 [106K]

Answer:

The sun's solar radiation and the wind's movements.

Explanation:

The heat from the sun and air movement is responsible for the weather on Earth. All-weather takes place in the lowest layer of the Earth's atmosphere, which is a gaseous layer that surrounds the planet. The heat of the sun causes the air in this layer to warm to various temperatures in different regions.
