Why do the chromosomes line up in the middle of the cell
Answer:
QUESTION:
Why do the chromosomes line up in the middle of the cell?
ANSWER:
Chromosomes line up at the metaphase plate, under tension from the mitotic spindle. The two sister chromatids of each chromosome are captured by microtubules from opposite spindle poles. In metaphase, the spindle has captured all the chromosomes and lined them up at the middle of the cell, ready to divide.
Explanation:
Hope that this helps you out! :)

Explanation:
Which of the following best predicts and justifies how the proportion of the Tibetan population with big blood vessels living in the mountains will change over the next 1,000 years (assuming conditions remain stable)?
Question 2 options:
I predict that the proportion of individuals with big blood vessels living in the mountains will decrease because there is a variation in blood vessel size and those with the smaller blood vessels can store more red blood cells than larger vessels, so more oxygen can be moved to the body cells. Therefore, they have a better chance of surviving and passing this trait on to their offspring.
I predict that the proportion of individuals with big blood vessels living in the mountains will stay the same because there is a variation in blood vessel size and that variation will remain in a population. The is what is so cool about humans, we are all so unique.
I predict that the proportion of individuals with big blood vessels living in the mountains will increase because there is a variation in blood vessel size and those with the bigger blood vessels can deliver more oxygen to the body cells and therefore have a better chance of surviving and passing this trait on to their offspring.
I predict that over 1,000 years, the proportion of individuals with big blood vessels living in the mountains will not change because a change can’t happen to an individual, an individual can only increase the amount of red blood cells it makes, not its blood vessels.
Answer:
Over 1,000 years, the proportion of individuals with big blood vessels living in the mountains will not change because a change can’t happen to an individual, an individual can only increase the number of red blood cells it makes, not its blood vessels.
Explanation:
Evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection
What is blood vessels?
The blood vessels are the components of the circulatory system that transport blood throughout the human body.
I predict that over 1,000 years, the proportion of individuals with big blood vessels living in the mountains will not change because a change can’t happen to an individual, an individual can only increase the amount of red blood cells it makes, not its blood vessels.

Why do we use specific terminology when referring to the gender and species of common domestic animals?
Answer:
To know which exact organism you are referring to, and there is no confusion about it.
Explanation:
To identify organisms, we usually use two names. The common name and the scientific one.
Scientific name: binomial nomenclature.
The scientific name designates a species through binomial nomenclature. The binomial nomenclature is a standard agreement used to identify different organisms. It has international validity, and it does not change among regions or languages. One binomial name is used only on one organism and can not repeat. It is composed of two Latin words: gender and the specific name. Many species might share the same gender for being very similar, so the specific name is used to identify each species.
Common names:
These are informal names, determined by the people of a region or area, that speak the same language. They are regional names, so they change from region to region, even when referring to the same organism. Usually, these names designate only organisms that have importance for the people. The same name might refer to different organisms, and in many cases, the same organism might receive many names. For this reason, there might be confusion when using only common names to talk about a species.
If we need to refer to a particular organism, we should always use the scientific name to avoid confusion. As it is internationally recognized and accepted, anybody can know which species you are talking about, independently of the region or the language. In most cases, people mention a species using the scientific name together with many of its common names.

What kind of information can scientist get from soft body parts that they cannot get from hard body parts?
Answer:
Function and working mechanism.
Explanation:
Information such as function and working mechanism etc can a scientist get from soft body parts that they cannot get from hard body parts because these soft body parts perform their work continuously and we can study it through a number of ways and methods. The working mechanisms of hard body parts can't be study because they are not visible to any instrument and occurs inside their structure so that's why function and working mechanism are the information given by the soft body parts.

How about decreasing the amount of water in blood affect blood pressure
Answer:
When you're very dehydrated, your blood volume can decrease, leading to a drop in blood pressure. When blood pressure drops too low, your organs won't receive the oxygen and nutrients they need. You could potentially go into shock.

Some antibiotics work by disrupting ATP production in bacteria. Which of the following will the bacteria lack when ATP production is disrupted?
A. genetic material for reproduction
B. energy to perform life processes
C. nucleic acids to make proteins
D. cytoplasm to diffuse oxygen
When there is a lack of bacteria at the time when ATP production is disrupted so here the energy is performed. Hence the option b is correct.
Reason of lacking bacteria:At the time when there is some kind of antibiotics work is done by disrupting ATP production in bacteria.
So the lacking of bacteria at the time when ATP production is disrupted so it is because of the energy to perform the life processes.
hence, the option b is correct.

Suggest reasons for the color patterns of the frog and its lack of color on the ventral surface.
Answer:
To save itself.
Explanation:
The color patterns of the frog and its lack of color on the ventral surface allows the frog to protect itself from their predators because the frog changes its colour and the predators are unable to see them. The color patterns of frogs and their lack of color on the ventral surface allow frogs to escape from their predators. If the frog does not change its colour, the predators will see them and the frog will be catch by its predators and feed on them so this is the reason that frog changes colour or the presence of colour patterns.
