They have unique combinations of chromosomes

They have unique combinations of chromosomes.

In organisms that reproduce sexually, a gamete is a haploid cell that unites with another haploid cell during fertilization Gametes, commonly known as sex cells, are an organism's reproductive cells.

A female is any individual that generates the bigger kind of gamete—called an ovum—and a male creates the smaller type—called a sperm—in species that produce two morphologically distinct forms of gametes, and in which each individual produces only one type.

The flagellum, a tail-shaped feature that enables the cell to propel and move, is what makes sperm cells, or spermatozoa, tiny and motile. On the other hand, each egg cell or ovum is sizable and non-motile.

Therefore, They have unique combinations of chromosomes.

Answer: Receptors.

Explanation: Receptors. Receptors are groups of specialised cells. They detect a change in the environment stimulus. In the nervous system this leads to an electrical impulse being made in response to the stimulus.

Receptors are the specialized cells in the nervous system that detect heat, pressure, and other environmental stimuli.

Receptors are proteins, usually cell surface receptors, which bind to ligands and cause responses in the immune system, including cytokine receptors, growth factor receptors and Fc receptor.

Moreover, receptors are bound up with functions such as cell activation, cell adhesion and signaling pathways. These functions play a role with the help of receptors.

Therefore, cell activation including T cells, dendritic cells, B cells, granulocytes and NK cells, is an important process in innate and adaptive immune system.

Answer:

The second answer choice.

Explanation:

Genetic variation must be the answer as the plants were grown in the same conditions. Therefore, the only source of variability might be genetic variation.

The first choice is not the answer because Genetic factors cannot cause the environment around the plant to change.

The third choice is not the answer because the Environmental factors are the same, and if they were really to cause a mutation, all three plants would mutate.

The fourth is the same reason as the third: if environemnt conditions affected the flower, all three plants would change color since they were all grown in the same environemnt, not just the one we see in the results.

Some significant floricultural species can now produce flowers with attractive and unique bloom hues thanks to recent advancements in genetic alteration techniques. Thus, option B is correct.

Flower color is governed by two primary gene families. Genes that code for the protein machinery needed to create pigment molecules are part of one category.

The second group includes genes that result in the production of regulatory proteins. The location, quantity, and kind of machinery that makes up the pigments are determined by regulatory proteins.

Flowers have genes that determine how they look, just like humans. These plants “give birth” to pigments, which result in a rainbow of hues.

The carotenoid substance that gives tomatoes and carrots their color also gives some flowers their yellow, red, or orange hue.

Therefore, Genetic factors caused the differences in flower color.

b number positive feedback

"A hole in the skin causes platelets to rush to the site and release a chemical that releases more platelets" is an example of a positive feedback mechanism. The correct option is B.

A positive feedback mechanism is a technique of the body in which the body works or secretes something to the body that is needed more in the body, and it is secreted in the body out of league and number.

Platelets are present in the blood. They are spherical and are colorless and small. They help in blood clotting when there is a cut or bleeding, it prevents loss of blood by clotting the blood.

So, in the hole of the body, there will be blood loss, and releasing more platelets would help in blood clotting.

Answer:

d. There is a net energy loss

Answer: The answer is C!!! :D maintaining homeostasis by regulating the body's temp!

Explanation:

Shivering as a natural, involuntary response to generate heat is an example of  maintaining homeostasis by regulating body temperature.

Homeostasis refers to the maintenance of a relatively constant body environment. The normal range of operation of the body system is known as the setpoint.

When the setpoint temperature for some animals is breached, a negative feedback mechanism is used to return it to the setpoint. Shivering to generate heat is a response to a cold environment when the body's temperature is about to drop below the setpoint.

The oppositeis sweating. Sweating causes cooling and comes in response to when the setpoint temperature is exceeded.

Hopes this helps happy early Christmas!!!! :D

Maintaining homeostasis by regulating body temperature.

Shivering is a mechanism used by animals, including humans, to maintain a constant body temperature in cold environments. When the body's core temperature drops below its normal range, shivering is an involuntary response that generates heat by rapidly contracting and relaxing the muscles.

This increased muscle activity requires energy, which is obtained from the breakdown of stored carbohydrates and fats, releasing heat in the process. This helps to raise the body's core temperature back to its normal range and maintain homeostasis, which is the body's ability to maintain a stable internal environment despite changes in external conditions.

Answer: different species

Explanation: They live in the same community like a Gouldian finch and a Double-Barred finch but are different species

However, one is nocturnal (awake at night) and the other is diurnal (awake in the day) as it consist of different species and they live in the same community like a Gouldian finch and a Double-Barred finch but are different species.

The hours of low light in the evening shows that it would be when humans would be most at risk from dangers. Species might make sense to seek shelter during this period.

As a result of their divergent evolutionary paths, various species have evolved in various ways to adapt to their habitats. The reason a certain species is nocturnal or diurnal has a variety of different potential causes. Perhaps at night, when light levels are low, when humans would be most exposed to dangers. The decision to seek sanctuary during this time may therefore be justified. Considering the various predatory dangers that mice and rats encounter, it is possible that being active at night reduces the threat posed by predators like birds who utilize their visual senses to identify prey.

Answer: I think the answer is d sorry if its wrong.

Explanation:

Answer:

A point mutation is a change in the base sequence of a DNA molecule.

Explanation:

The most likely conclusion that can be made for the change in flower color is that genetic factors caused the differences in flower color.

According to this question, three plants are grown in the same environmental conditions with equal sunlight, water, and space to grow.

However, despite the uniformity in the environmental conditions received by each plant, one plant grew to have a purple flower while the other two grew white flowers.

This difference in flower color is likely caused by the inherent genetic factors of each plant rather than environmental factors because they were treated the same.

Burning of fossil fuels adversely impacts on the water cycle that adversely affect the climate on Earth.

Human activity such as the burning of fossil fuels in vehicles and burning of wood for cooking have adverse effect on the earth's atmosphere. This burning of fossil fuels increase the temperature of the earth leads to global warming.

Raising the Earth's temperature means that there is an increase of evaporation, melting of glaciers and sea ice which imbalance the water cycle leads to flood and drowning of coastal regions of the earth so we can conclude that burning of fossil fuels adversely impacts on the water cycle that adversely affect the climate on Earth.
