Question

What are chromosomes?

Answer:

Chromosomes are thread-like structures found within the nucleus of both animal and plant cells. Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA). DNA is passed along from parents to children and carries the precise instructions that distinguish each living thing.

The word "chromosome" is derived from the Greek terms "chroma" and "body" (soma).

To determine the density of a rabbit population, one would need to know the number of rabbits and __________. View Available Hint(s) To determine the density of a rabbit population, one would need to know the number of rabbits and __________. their pattern of dispersion the size of the region in which they live the factors that limit population growth for that rabbit population the growth rate of the population the birth rate

Answers

Answer:

The growth rate.

Explanation:

To determine the density of a rabbit population, one would need to know the number of rabbits and the growth rate of rabbit's population because both factors allow us to determined the population of rabbit in a specific region. If we know the existing population of rabbits in a particular area as well as the growth rate at which the rabbit population increases so we can find out the density of rabbit population in a specific time period.

Three reasons that might have influenced authorities in the department of agriculture to use a higher percentage of Nguni on the communal and emerging sector of livestock farmers in South Africa in 2003

Answers

Answer:

Tolerance to heat, light and parasite.

Explanation:

Characteristics of tolerance to heat, light and parasite are the three reasons that might use a higher percentage of Nguni on the sector of livestock farmers in South Africa in 2003. The temperature of South Africa is extremely high which can be tolerated by the Nguni cattle due to its good characteristics. The Nguni cattle can bear extreme temperature, high intensity of light and resistance to parasites make it best suited for that environment.

As surface water in a lake cools from 4 °C to 0 °C, the water expands and becomes less dense. Why is this change in the water beneficial to the organisms living in the lake? As the water cools to freezing, spaces form between water molecules, providing microhabitats for small organisms. Frozen surface water insulates the water below it, maintaining a habitat where organisms can overwinter. Cooler water is less viscous than warmer water, making it easier for organisms to move through the water. Less dense water holds more dissolved compounds, keeping water from freezing so organisms survive winter.

Answers

Answer:

As the water cools to freezing, spaces form between water molecules, providing microhabitats for small organisms.

Explanation:

This change in the water is beneficial to the organisms living in the lake because the water which freezes formed spaces between water molecules, that providing microhabitats for small organisms. The cold temperature causes formation of ice crystals on the surface of water which work as an insulator whereas the lower part of the water remain warm and the organisms can survive in that environment.

Reproduction for dolphins and badgers and people is more complicated because
A. we have to apply for a license before we can reproduce

B. have to find a partner

C. go through the cellular process of MITOSIS to produce sex cells.

Answers

Answer:

B. have to find a partner

Explanation:

When two badgers get together and fall in love, a sperm cell from the father which contains a copy of half of his DNA, only half, combines with the egg cell of the mother, which contains half a copy of her DNA. The result is a brand new cell with all the information to divide and grow up into a brand new badger. The new child matures to be similar to our parents, but also unique, because she developed some traits from her mother’s DNA, and some from her father. Her new combination of traits can be passed on to her children, and again.

Consider this plant cell. The organelles in a plant cell are labeled. Part G is the middle layer of the cell. Which organelle is labeled G?

Answers

Answer:

Hi. You didn't show the picture that shows organelle G, but since you showed that organelle is the middle layer of the cell, we can say that it is the plasma membrane.

Explanation:

In general, we can state that the plant cell has three layers, the cell wall, the plasma membrane and the cytoplasm. The cytoplasm is the inner layer, where most of the organelles and the cell nucleus are located. Above the cytoplasm is the plasma membrane, which is semi-permeable and promotes the regulation of the entry and exit of substances from within the cell. Above this membrane is the cell wall, which is an impermeable structure that protects the cell and promotes its rigidity. In this case, we can consider that the middle layer of the cell is the plasma membrane.

O B. Some iguanas are better swimmers than others.

O C. The species arrived on the islands in different ways.

OD. The species adapted to each island's unique habitat.

Answers

OD because they acquired adapted traits to better suit them in their environment

The statement that explains each island in the Galapagos has unique kinds of iguanas is that the species adapted to each island's unique habitat. The correct option is D.

What is adaptation?

Adaptation is defined in biology as a heritable behavioral, morphological, or physiological trait that has evolved through natural selection and maintains or increases an organism's fitness under a given set of environmental conditions.

To survive, all organisms must adapt to their surroundings. This entails adapting to the climatic conditions of the ecosystem, predators, and other species that compete for the same food and space.

The marine iguana is the only lizard in the world that can live and forage at sea, and it is only found in the Galapagos Islands.

There are eleven very similar subspecies found on various islands, with Isabela and Fernandina having the most. The species adapted to the distinct habitats of each island.

Thus, the correct option is D.

The microscopes we use today are far more complex than those first microscopes like the one used in the 1600s by Anton van
Leeuwenhoek. Despite the limitations of his simple microscope, van Leeuwenhoek observed some cells he termed
"animalcules." Robert Hooke then coined the term "cell" for the box-like structures he observed when viewing cork tissue
through a lens. Later advances in lenses, microscope construction, and staining techniques enabled other scientists to see
some components inside cells. Just as the microscope has been a work in progress with advances that have led to our current

What is microscope?

The instrument that is used to observe tiny particles as well as objects or cell of the body has been known as microscope. One lens in the microscope has been used to magnify the image at least once. The main function of the lens has to bend the light in the direction of the eye and forms the larger image of the object.

There are several types of microscope and these are electron microscope,scanning probe microscope, stereomicroscope, simple microscope, and light microscope.The main function of the lens has to bend the light in the direction of eye and forms the larger image of the object.

Each microscope have different function and ability to observe the object. As we know that the size of the cell has very small and it has impossible to observe it without microscope. So, microscope helps to observe the interior part of the cell and it will help in the study of different part of cell.

Therefore, The microscopes we use today are far more complex than those first microscopes like the one used in the 1600s by Anton van Leeuwenhoek.
