Which of earths layers is shown by the letter Z in the image above?u

Answer:

They are made of protein and one molecule of deoxyribonucleic acid (DNA). As the genetic material passes from parents to child, the chromosomes are responsible for containing the instructions that make the offspring unique while still carrying traits from the parent.

The primary function of chromosomes lies in the fact that; DNA is tightly packaged within them.

Discussion:

Chromosomes are thread-like biological structures within which DNA is tightly packaged in the nucleus.

Chromosomes help ensure that DNA is replicated and distributed appropriately during cell division.

Each chromosome has a centromere, which divides the chromosome into two portions.

Answer:

Cytokinesis is a phase in which two daughter cells are separated from one another.

Explanation:

Cytokinesis is a phase in which cytoplasm of the cell is divided into two equal parts after the cell division i. e. mitosis or meiosis. Cytoplasm is a main part of the cell which contains different organelles of the cell such as mitochondria, ribosome, endoplasmic reticulum, golgi bodies, lysosomes and vacuole etc. It also contains nutrients, enzymes and water in large amount.

Final answer:

The two daughter cells are physically separated during cytokinesis, which is the final step of the mitotic phase of the cell cycle.

Explanation:

During which phase are the two daughter cells physically separated? This occurs in the mitotic phase of the cell cycle. Specifically, the physical separation of the two new daughter cells is completed during cytokinesis. First, mitosis divides the duplicated DNA into two sets and distributes them into separate nuclei. Following this, cytokinesis divides the cytoplasm, resulting in two new cells that are genetically identical to the original cell. It's important to note that while mitosis (karyokinesis) occurs in the mitotic phase, cytokinesis can sometimes take place independently, leading to cells with multiple nuclei (multinucleate cells) when cytokinesis does not occur.

C. Temperatures are dropping because greenhouse gases are low and constant

Explanation:

I took the test and got it correct

C. Temperatures are dropping because greenhouse gases are low and constant.

Temperatures drops due to lowering constantly of greenhouse gases in the atmosphere. Greenhouse gases has the ability of trapping solar radiation after reflecting the earth surface. This trapping increases the temperature of the surrounding environment so if the temperature decreases it is due to lowering of greenhouse gases so we can conclude that temperatures are dropping due to lowering of greenhouse gases.

The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other. They move at a rate of one to two inches (three to five centimeters) per year.

Answered below

Explanation:

Collecting a patient's stem cells and using them for their treatment is known referred to as autologous stem cell transplantation. In autologous stem cell transplantation, stem cells are harvested in the patient's bloodstream or the bone marrow and used to treat or grow organs for the patient.

Using stem cells harvested from your own body is advantageous over stem cells collected from a donor. This is because the case of incompatibility is eliminated. There is also less risk of rejection of organ or graft versus host disorder, where the donor cells attack the host cells thinking they are foreign bodies.

There are fewer side effects and quicker engraftment and therefore quicker recovery.

Answer:

This is because it prevents organ rejection during transplant. so far the new organs share the same stem cells with the patient.. ;like cells, like tissues will not give rise to immune response which usually lead to rejection.

It also saves time, and ensures survival since there is no need to wait for a compatible donor, before the transplant can be possible.  

Explanation:

When a car is slowed, the kinetic energy is primarily converted to thermal energy due to the friction between the brakes and the wheels. However, in hybrid vehicles, some of this energy can also be converted into electrical energy and stored in batteries.

As a car is slowed, most of its kinetic energy is converted by the brakes to thermal energy. This occurs because the brakes use friction to reduce the car's speed, transforming the motion energy into heat energy. This is apparent when after a car is brought to a stop, the brakes can become very hot. This heat is a form of dissipated energy and is no longer available to do mechanical work, such as moving the car.

In the case of hybrid vehicles, this concept is further utilized, where the brakes convert mechanical energy into electrical energy, which is then stored in the battery.

Selective Breeding

Explanation:

Selective breeding is a process where to get the best result, you breed the best children. By breeding the smallest babies together again and again slowly the children will become smaller and smaller as the parents get smaller and smaller

I hope this helps u!

pls give a brainliest and a thx ;)

The process described in the question is selective breeding, used to create dog-sized elephants for the exotic pet trade. While it might fulfill certain human desires for unique pets, this practice raises significant ethical, health, and biodiversity concerns.

The scenario described involves a process known as selective breeding or artificial selection, where certain traits, in this case, smaller size, are chosen to be passed on to future generations. This methodology has been used in creating various miniaturized pet breeds such as "teacup" dogs, which are known for being small enough to fit in a pocket. However, the process of achieving extreme miniaturization comes with a myriad of health risks, including but not limited to collapsing tracheas, heart defects, and dental problems. The case of breeding dog-sized elephants for the exotic pet trade raises ethical concerns, not only due to the health issues associated with selective breeding but also because of the impact on biodiversity and the implications of wild animal trade.

Exotic pets, especially those taken from wild populations, contribute to biodiversity loss and can be at high risk of extinction, which is magnified by the demand in the pet trade.

Explanation:

Answer: insects helps plants reproduction through pollution, which further leads to fertilization, flower and seed production.

Explanation:

Answer: Many flowering plants have separate male and female flowers. Therefore, they need help transferring the pollen from one flower to another, so they rely on pollinators to help with pollination. A pollinator is an animal, such as an insect or a bird, that transfers pollen from flower to flower. Plants have flowers that attract pollinators in many ways. They produce nectar that birds such as hummingbirds eat. They have bright colors, "nectar guides,” and patterns that look like bull’s-eyes to guide insects, such as bees, into the flower. Once the animal is inside the flower, it gets covered with sticky grains of pollen. As the animal moves from flower to flower, pollen brushes off onto the stigmas of other flowers. Fertilization can then occur to produce seeds.

Explanation:

The relationship between natural selection and adaptations is natural selection is the process leading up to adaptations in a population.

The mechanism that makes it more likely that future generations will have advantageous traits is known as natural selection. The trait that adapts to the environment is called adaptation.

The possibility of regular choice is that characteristics that can be passed down permit creatures to adjust to the climate better than different organic entities of similar species.

Many finches perished because their smaller beaks were unable to crack the tough seeds. Through the course of regular determination, the birds that had the option to adjust replicated and flourished, while the others dwindled in number.
