The homologous chromosomes separate during ____________________ and their sister chromatids separate during _____________ phase of meiosis.
Answer:
anaphase I chromosomes separate
anaphase II sister chromatids separate
Prophase I and metaphase I are the first two stages of meiosis I, respectively. Two kinetochore microtubules from each of the two opposite poles bind to the bivalent chromosome's centromere during anaphase II.
What are the characteristics of anaphase I and anaphase II?The centromeres of each chromosome simultaneously separate during the anaphase II stage of meiosis II, and the sister chromatids are drawn apart in the direction of the opposing poles.
A microtubule network referred to as the spindle apparatus is used to transport chromosomes to both poles of a meiotic cell at this stage. Through this technique, two distinct groups of homologous chromosomes are formed.
Therefore, The homologous chromosomal pair's individual kinetochore-microtubules are joined to each chromosome during anaphase 1.

When looking at the sequence of a variety of genes, which species' genes would you predict to have the most similar sequence compared to the corresponding genes in humans
Answer:
Explanation:
One of the most important aspects of bioinformatics is identifying genes within a long DNA sequence. Until the development of bioinformatics, the only way to locate genes along the chromosome was to study their behavior in the organism (in vivo) or isolate the DNA and study it in a test tube (in vitro).

By analyzing a phylogenetic tree, we can establish relationships between different taxonomic groups. Nodes, branches, and lineages provide information for these interpretations. The statements are C and E.
--------------------------------------
The phylogenetic tree is composed of,
Lineages → The taxonomic groups of interest. These are placed in the extremes of the branches. Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor. Root → This is the older common ancestor that all lineages share. The first one in the tree.
⇒ Highly related groups that share a recent common ancestor. This means that they all diverge from the same node.
⇒ Lineages less related to each other are those whose common ancestor is far away in history.
A) Gray whales are the common ancestor of the Blue and Humpback whales. ⇒⇒⇒ NO
B) Blue and humpback whales diverged more recently than either did from
the gray whale ⇒⇒⇒ NO
C) The Bryde's whale shares a more recent common ancestor with the Sei

Additionally, bacteria are vital components of the Earth's ecosystems since they are present in food, water, soil, and surfaces.
What distinguishes a bacterium from a bacteria?The word "bacteria," which is plural, is spelled "bacterium." To put it another way, you use the word "bacteria" when there are multiple of them and "bacterium" and there is only one.
Why do bacterial infections occur?When bacteria taken into the body, multiply, and trigger an immune response in the body, a bacterial infection results.

Prokaryotes are important to all life on Earth for a number of reasons.
Explanation:
They play a critical role in the recycling of nutrients by decomposing dead organisms and allowing their nutrients to be re-used.
They are also important for many metabolic processes. Bacteria in our guts and mouth help with the digestion of food by breaking down difficult to digest carbohydrates and other compounds. Recent research has suggested that the microbial community in our guts can be a significant factor contributing to obesity.

Explanation:
consider a stable frog population living at carrying capacity in a pond. an average female produces 6,000 eggs during her lifetime and an average of 300 tadpoles hatch from these eggs. for the population size to remain stable, how many of these tadpoles should, on average, survive to reproduce?
Answer:
Uhmmmm, Since out of 6,000 eggs, 300 would hatch on average. The amount of tadpols to most likely survive would be 10-30. (I think)
The same species in an ecosystem living in a group is called population. The attribute of the population is the sex ratio, population, birth ratio, and death ratio.
The answer is 5% of the tadpole.
The fusion of the male and female gamete is called reproduction which leads to the formation of new offspring which carry the genes to the next generation.
To remain stable in the population is 5% of the tadpole because the tadpole formed survive after the egg is 5% of the total.
Hence, the 50 tadpoles must survive to have a stable population.

Answer:
A polygenic trait is controlled by multiple genes and influenced by the environment.
Explanation:
A Polygenetic trait is a group of non-epistatic genes that interact to influence a trait. Essentially, in short terms Polygenetic traits are controlled by multiple genes rather then an individual inherit gene.
Hope I helped,
Brainliest is always appreciated.
Answer:
B: A polygenic trait is controlled by multiple genes and influenced by the environment
Explanation: For anyone who wants/needs an explanation
Polygenic traits basically mean the traits that are a result of multiple intertwined traits like for example skin colour.
When two people mate their traits get intertwined and the resultant trait of the baby is a result of the polygenic traits.
Polygenic traits are controlled by more than one genes. An example of this on humans is height. Not one gene controls the height of a human, many traits contribute to the height of a human.
