a. According to Model 3, which of the following diagrams correctly show an original set of
homologous chromosomes (grey) and their sister chromatids (black)—the replicated portion?
ХХ ХХ ХХ ХХ

Answers
The diagrams to answer the question are missing. However, an original set of homologous chromosomes and their sister chromatids should look like a column of one color for the homologous and another column of the same color but join with the original column by the centromere for the sister chromatid.
A chromosome is a molecule of DNA; it stores and transmits genetic information. Chromosomes have different parts and structures.
A homologous chromosome is:
A pair of DNA molecules that have two different genetic information.Each chromosome comes from one progenitor. It has its respective genetic information.A sister chromatid is:
The replication of the homologous chromosome. They carry the same information.
In conclusion, an original set of homologous chromosomes and their sister chromatids will look like the one shown in the image. Two lines of a different color for the homologous chromosome and "X" of the same color for the sister chromatid, since it is a chromosome that it replicated itself and is joined to the original one by the centromere.

How tall is Sam in (METERS)? Please Show Your Work! ^^
Answers
Answer:
You can just ask the web, it is ur bestie and will always be there for you, okay? <3
Answer:
1.55m
Explanation:
Because there are 3.28 feet in a meter, take your measurement (in feet) and divide it by 3.28 to convert to meters. You can also multiply your measurement in feet by 0.3048 to get the exact same answer because there are 0.3048 meters in a foot.
5 feet + 1 inch = 150 centimeters = 1.5494 meters
(5"1' = 154.94 cm = 1.5494 m)
How to Convert 5 feet + 1 inch to cm or m?
Please follow these steps:
Multiply the value in feet by 30.48 to get the result of the conversion of feet in cm:
5 x 30.48 = 152cm
Multiply the value in inches by 2.54 to get the result of the conversion from inches to cm:
1 x 2.54 = 2.54cm
Now, add the two partial results to obtain the final value in cm:
152 + 2.54 = 155cm.
Divide the value 1.55cm by 100 to get the result in meters.
155 Divide the value 1.55cm by 100 to get the result in meters.
155
100
= 1.55m

Answers
One of the functions of the skin is to maintain body temperature. Therefore, the correct option is A.
What is skin?The skin of an organism is considered to be the largest of all the organs of the body. It plays a crucial role in maintaining body temperature by regulating heat loss from the body.
When the body is too warm, the blood vessels in the skin dilate, allowing heat to be released from the body through the skin's surface. When the body is too cold, the blood vessels in the skin constrict, reducing heat loss and helping to maintain body temperature.
While the other organs listed also have important functions in the body, such as pumping blood (heart), detoxifying the blood (liver), and controlling bodily functions (brain), they are not primarily responsible for maintaining body temperature. Therefore, the correct option is A.

What is biodiversity and why is it important?There are different ecosystems, and each ecosystem consists of certain animals and plants that create biodiversity, there are migrations of organisms that result in the sharing of genes, and some of the exotic species, such as flowers, are taken for commercial purposes. Simultaneously, poaching of animals, such as elephants for their tusks, is a major concern, so captive breeding is used to stop species loss and preserve their habitats, and by the germ-plasm theory, they reproduce and then produce the zygote.
Hence, in the ecosystem, there is biodiversity seen in plants and animals, and these can share their genes, but due to animal hunting, habitat loss is a concern, so to preserve their habitats, the captive breeding program is done.

The rate of human population growth accelerated shortly after the discovery of antibiotics, primarily as a result of medical science advances. By the middle of the 20th century, child mortality rates also abruptly decreased, but the birth rate remained extremely high.
What factors affect growth, survival of human populations?These elements frequently contribute significantly to population survival. From day to day or season to season, some variables alter. Some may change over numerous years, such as predation and food availability.
The three elements of change are migration, births, and deaths. Natural rise or natural change are terms used to describe the change in the population caused by births and deaths. Depending on whether more individuals are added than are removed, populations either increase or decrease.
Therefore, Rainfall, temperature, predators, shelter, and food supply are examples of environmental elements that can alter.

Answer:
repeat the same experiment and obtain the same result
explanation...
Getting the same result when an experiment is repeated is called replication. If research results can be replicated, it means they are more likely to be correct.
Replication is important in science so scientists can “check their work.” The result of an investigation is not likely to be well accepted unless the investigation is repeated many times and the same result is always obtained.

Adaptations are phenotypes that improve reproductive success; such phenotypes might arise as a result of ______ followed by ______ over many generations.
Answers
Adaptation is a phenomenon that occurs when an organism becomes comfortable or fitted to its environment without suffering any adverse effect.
Adaptations are phenotypes that improve reproductive success; such phenotypes might arise as a result of mutations in DNA followed by natural selection over many generations.
For a change that occurs in an organism environment, the organism needs to find ways to adapt to such environment.A favourable change in the DNA (mutation) might then occur enabling them to adapt successfully.This favourable change will then be selected for due to natural selection as the change is heritable enabling the survival and reproductive success of the organisms.Learn more: https://brainly.com/question/17810004
