Answer:
Centromere
Explanation:
Connects sister chromatids
The structure labelled A in the figure is a centromere.
What is a centromere?The centromere is a region of the chromosome that is constricted. The centromere plays an important role in the division of cells during both the processes of mitosis and meiosis.
The centromere is simply the region of the chromosome where the spindle fibres attach. Therefore, when the spindle fibres attach to the centromere, they pull the sister chromatics in the opposite directions of the cell during cell division.
Thus, at the end of the cell division, each of the daughter cells gets one-half of the chromosome containing identical DNA. The centromere is thought to be the middle region of the chromosome, even though it is often not in the middle. It is simply the region where the chromosomes are most constricted
The centromere separates the chromosome into the P arm and the Q arm. These are simply the names given to the short arm and the long arm of the human chromosome respectively.

What effect did the human population have on Easter Island? How did they change the island's natural cycling of matter and energy?
Answers
Answer:
The population history of the island remains highly controversial. In addition to internal conflict, the population crash has been attributed to “ecocide,” in which the Island's resources were exhausted by its inhabitants, reducing its ability to support human life.
Explanation:
Europeans was known to discovered Easter Island in 1722 and it's name was given by Captain Admiral Jacob Roggeveen.
The human population growth had a negative effect on the Easter Island.
The ecocide hypothesis is the one explanation to how the human population increased exponentially since its colonization and as such
Human populations did over increased the carrying capacity of the Island to support sustainable crops, and in consequence, the island was severely deforested.
The island's natural cycling of matter and energy also reduced or change and as such the people fought among themselves for scarce resources of the island. They had little food and were starving and they resorted to cannibalism.
The island was also plaque by blackbirding from 1862 to 1863.

The relationship between a carnivore and an herbivore can be stated as B predator and prey.
What are the predator and prey ecological relationships?The predator and prey ecological relationships can be defined as ecological associations in which an organism serves as food for others in the food web, thereby leading to the homeostasis of the whole system in the food chain.
Therefore, with this data, we can see that predator and prey ecological relationships are based on different trophic levels where one organism situates below in the food chain is the prey of another.

A researcher in 2024 studies the evolutionary relationships between influenza viruses by comparing the genomic sequences of the viruses found in pigs, ducks, and humans in a given year. When evaluating the viruses that had infected these hosts the previous year, she identifies a cross-species transfer from pigs to ducks in the year 2022. What information supports the hypothesis that cross-species transfer leads to more severe disease in the new host
Answers
Answer:
pigs suffered severe influenza in the year 2022
Explanation:
Influenza, commonly known as flu, is a viral infectious disease caused by different types of influenza viruses. Some of the most common symptoms of this disease include, among others, headache, coughing, fever, muscle pain, etc. Influenza viruses can affect humans and different animals such as, for example, cats, dogs, birds and horses. There is evidence showing cross-species influenza virus transmission. For example, it has been shown that the influenza type A virus can be transmitted from one species to another (for example, between humans and pigs). In these cases, cross-species transmission information may indicate how much potential a virus has to cause a pandemic in the new host by analyzing the severity and infectivity of the virus in the original host.

Answers
Answer:
review all proposals for animal research to be sure the procedures to be used are appropriate and humane.
Explanation:
The Institutional Animal Care and Use Committee (IACUC) is a federal committee responsible for approving and/or prohibiting the use of animal (nonhuman vertebrate) subjects for research, testing and teaching purposes, as well as the inspection of animal facilities. IACUC evaluates the institution's animal programs and procedures as described by the Office of Laboratory Animal Welfare (OLAW). This committee has the task to verify animal's well-being by minimizing pain and distress (for example, by ensuring the use of non-invasive methods when possible). Researchers/educators that use animals for research/teaching purposes must previously submit a written request defined by the IACUC's guidelines.

Inorganic, crystalline substances found naturally within earth are known as
Answers
Answer:
Minerals.
Explanation:
Minerals can be defined as any form of naturally occurring, inorganic solid substance characterized by a crystal structure. Also, minerals are homogeneous in nature with a defined chemical composition and characterized by a crystal structure comprising of ions, atoms, or molecules in an orderly arrangement.
Generally, molecules attach on the inside of a mineral to give it shape. Therefore, the molecule of a mineral is a crystal three-dimensional regular structure (arrangement) of chemical particles that are bonded together and determines its shape.
Due to the fact that these molecules are structurally arranged or ordered and are repeated by different symmetrical and translational operations they determine the shape of minerals.
Hence, inorganic, crystalline substances found naturally within earth are known as minerals. Some examples of minerals are iron, copper, aluminum, tin, coal, quartz, feldspar, mica, etc.
