Is a chromatid a homologous pair?

Answers

Answer 1

No, a chromatid is not a homologous pair because a chromatid is one of the two identical halves of a chromosome.

The bivalent is a structure which is formed by a pair of synapsed chromosomes in the pachytene stage of prophase I of meiosis I. Each bivalent consists of one pair of homologous chromosomes. Each of these homologous chromosomes have two sister chromatids attached at the centromere.

At meiosis, each of the homologous chromosomes is comprised of two identical chromatids joined together by a common kinetochore (centromere). The identical chromatids are specifically called sister chromatids to distinguish them from the so-called non-sister chromatids. Sister chromatids are genetically identical, whereas homologous chromosomes are composed of two different chromosomes that are not genetically identical despite containing the same sets of genes.

The brown-colored bones in each animal help to connect their limbs to a specific joint in the torso, or middle of their body. What type of structure do these bones represent, and what is their significance in terms of evolutionary relationships?

Answers

Answer: These structures connect their limbs to a specific joint in the torso or in the middle of their body. These structures can be identified as homologous, they are morphologically similar or possibly they derive from a common ancestral structure.

Explanation:

The brown color bones in animal help to connect limb homologous structures that connect their limb to the specific joint in the torso, this and having an evolutionary relationship.

What are bones?

If two bones split where they meet at a joint, it is termed a dislocation. The place where two bones connect and therefore can move is called a joint.

A displaced joint is one where the bones are out of alignment with each other having a significant role in evolution.

Despite their similar arrangements and being formed in a similar way throughout embryonic development, these structures have slightly different shapes and purposes, they refer to them as homologous structures.

Therefore homologous structures have an evolutionary relationship to connect brown-colored bones connect limbs to joint torso.

If two-hybrid Ff rabbits mate, what will the offspring look like?

Answers

Answer:

25% FF - homogenous dominant

25% ff - homogeneous recessive

50% Ff - heterogenous

Explanation:

When two-hybrid Ff rabbits mate, then the offspring look like

25% FF - homogenous dominant25% ff - homogeneous recessive50% Ff - heterogenous.

What is Mating?

For the goal of sexual reproduction, opposite-sex or hermaphrodite organisms team together during mating. Two gametes join together during fertilisation. When two sexually reproducing creatures join their sex organs, internal fertilizations and insemination take place.

Punnett Square situations with two hybrid parents marrying are frequent. The heterozygous hybrid parents possess a single allele (A and a, Dominant and Recessive). There are four genotype outcomes that can happen if two hybrid parents mate.

Thus, when two-hybrid Ff rabbits mate, then the offspring look like

Answers

Answer:

this primate must be a species of prosimian, as that suborder of primates still relies heavily on the sense of smell for many aspects of daily life

Explanation:

The suborder prosimian belongs to primate mammals and is at a level inferior to the real monkeys.

Prosimians characterize as having an elongated head that culminates in the snout. They have big eyes with modifications in the retina that improve sight during the night. They are quadrupeds with a svelte body and soft hair. Their tail is long but not prehensile. They move from tree to tree by making use of their extremities. They have a dental comb to clean themselves and others.

Their snout is humid, and the sense of smell is much more developed than in other primates. They are the primates with the greatest sense of smell. Their olfactory bulb and glands are remarkably developed in concern with other primates. With their tree and nocturnal habits, they depend a lot in this sense to move, relate, be aware, and feed.

"Aardvarks and anteaters both use long, sticky tongues to capture and eat ants or termites. Aardvarks are native to Africa, while anteaters are native to the Americas. However, their similarities provide evidence that both groups of species evolved from a common ancestor that used its tongue to eat ant-like insects."

Which claim, if supported by evidence, would provide the strongest counter-argument AGAINST Cory's argument?
A. The tongues and diet of aardvarks and anteaters are an example of convergent evolution.
B. The tongues and diet of aardvarks and anteaters are an example of adaptive radiation.
C. The Americas and Africa were once joined together, and animals roamed freely between the two lands.

A consumer in a food chain is a living being that consumes organisms from another population. A heterotroph is a consumer, and an autotroph is a producer.

As in the notes it is mentioned that ferns are eating beetles, and snakes are eating finch. It is lacking secondary consumers eating primary consumers.

Answers

Answer:

Transcription factors

Explanation:

This is because Eukaryotic gene expression is regulated by transcription factors and RNA processing, which occur in the nucleus, and during protein translation, in the cytoplasm.

Transcription in eukaryotic cells is controlled by proteins . These proteins then bind to some specific regulatory sequences and try to control the activity of RNA polymerase. The Gene expression is regulate by transcriptional regulatory proteins . Also ,the packaging of DNA into chromatin and methylatiin indicate levels of complexity to the control of eukaryotic gene expression.

If data for the growth of this bacterial population continued to be recorded, would the data point at 60 hours be above or below 37 million? Support your answer.

Answers

Answer:

Above 37 million

Explanation:

Explanation in picture below

Growth of bacterial cultures is defined as an increase in the number of bacteria in a population rather than an increase in the size of individual cells.

Thus, Bacterial population growth occurs geometrically or exponentially: in  each division cycle (generation), one cell produces 2 cells, then 4 cells, then 8 cells, then 16, then 32, etc.

The relationship shows that the average generation time is constant and  the growth rate of the bacterial population is proportional to the number of bacteria at any given time.

This relationship is valid only during the period when the population grows exponentially, ie. in  the logarithmic phase of growth. Therefore, graphs showing the growth of bacterial cultures are plotted as the logarithm of the number of cells.

Thus, Growth of bacterial cultures is defined as an increase in the number of bacteria in a population rather than an increase in the size of individual cells.

Most nonrenewable energy resources are burned for us to use their energy. Which of the following is a nonrenewable energy source that is NOT burned?
A) nuclear

B) coal

C) natural gas

D) biofuels

Answers

Answer:

The correct answer is - A) nuclear.

Explanation:

Most of the non-renewable sources of energy are fossil fuels that are formed by the thermal decomposition of dead organic matter for million years and are converted to lighter hydrocarbons that contain high electrostatic potential energy.

Burning is the process that breaks the hydrocarbons into water vapor and CO2 with high amount of energy. Coal, natural gas and biofuels all three are fossil fuels and nuclear products are not fossil fuel but radioactive elements.
