Answer:

The answer is homologous chromosomes.

Explanation:

Two choromosomes in a nucleus which carry genes that control the same inherited characteristics or phenotype are called homologous chromosomes.

I hope this answer helps.

Answer:

The correct answer is: homologous chromosomes.

Explanation:

Diploid species like us humans have two sets of the same 23 chromosomes: 1 set of chromosomes is inherited from our mother, the other set we inherit from our father, making up a total of 46 chromosomes in every somatic cell (sexual cells have only one set of chromosomes - they're haploid).

<u>Two chromosomes are </u><u>homologous</u><u> when they belong to the same pair and have the same genetic information, although they can have a few variations</u>. These variations from one homologous chromosome to the other are called<em> alleles</em> and represent the different phenotypic variables that can result from the same gene. If these alleles are different from one another, only one of them will express itself (there are a few exceptions, like blood type) as the organism will be heterozygous for this trait; if the alleles are the same, the individual will be homozygous for the trait.

This is the basis for Mendelian inheritance.

Vaselesa [24]

Answer:

Potential targets:

1- DNA methyltransferases

2- Chromatin modifiers such as histone acetyltransferases, histone deacetylases, histone methyltransferases, etc.

3- Components of the RNA interference (RNAi) machinery such as Dicer, Argonaute, etc.

Explanation:

Epigenetics can be defined as the study of any heritable change in the phenotype that does not involve modifications in the DNA sequence. Epigenetic mechanisms can be classified into three major types: 1-DNA methylation, 2-histone modifications (e.g., acetylation, methylation, phosphorylation, etc), and 3-regulatory non-coding RNAs (e.g., miRNAs, lncRNAs, siRNAs, etc) that modulate target gene expression via the RNA interference pathway. There are different types of proteins that are involved in these complex epigenetic mechanisms, and those cited above represent only some examples that can be used as therapeutic targets.

Explain briefly how these features contribute to the efficiency of photosynthesis?​
barxatty [35]

Answer:

here's your answer

Explanation:

the estimated maximum energy efficiency of photosynthesis is the energy stored per mole of oxygen evolved, 117/450, or 26 percent.

Consequently, plants can at best absorb only about 34 percent of the incident sunlight. The actual percentage of solar energy stored by plants is much less than the maximum energy efficiency of photosynthesis. An agricultural crop in which the biomass (total dry weight) stores as much as 1 percent of total solar energy received on an annual areawide basis is exceptional, although a few cases of higher yields (perhaps as much as 3.5 percent in sugarcane) have been reported. There are several reasons for this difference between the predicted maximum efficiency of photosynthesis and the actual energy stored in biomass. First, more than half of the incident sunlight is composed of wavelengths too long to be absorbed, and some of the remainder is reflected or lost to the leaves

How much energy must these squid and small fish consume to sustain the elephant seal population
Inessa05 [86]

Answer:

<em>Well, Since the elephant seals consume 200,000 calories from the squid and small fish, this means that the squid and the small fish get 2,000,000 calories from their food, thus they are able to sustain the population of elephant seals. Hope That Helps!</em>

Which is the best explanation for why there is a continued need to develop new antibiotics to fight bacterial infections?
prisoha [69]

Answer:

Today, drug-resistant infections are a serious threat to people's health. Hundreds of thousands of lives are lost every year because of infections that can no longer be treated with existing drugs. Discovering new antibiotics, able to kill drug-resistant bacteria, is essential to saving modern medicine.
