So why the gametes in a single plant are genetically different from each other and also different from the cells in the rest of the plant
Is my answer correct ?
Explanation:
They have unique combinations of chromosomes
They have unique combinations of chromosomes.
What are gametes?
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:
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.
What is a positive feedback mechanism?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.

Which option distinguishes the outcome if the Farm Bill were to end subsidies to private growers, but continue to provide food stamp funding?
Wholesale commodities prices would increase and create a devaluing of food stamps.
Food stamp recipients would replace subsidies by spending more money on agriculture.
Farm prices would drop due to a higher supply of unsold goods but no demand change.
Aid would shift and all farmers receiving subsidies would receive food stamps instead
Which of the following human actions negatively affect the water cycle by increasing evaporation?
Answer: Hydroelectricity
Explanation: None Sorry
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.

Some animals shiver as a natural, involuntary response to their environment. Shivering generates heat. This is an example of which function? reducing movement to regulate body temperature reducing movement to regulate blood glucose maintaining homeostasis by regulating body temperature maintaining homeostasis by regulating blood glucose
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.
What is shivering?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.

What are the types of energy ?The energy can be defined as ability to work or produce action and / or movement and manifests itself in many different ways, such as body movement, heat, electricity, etc.
The different types of energy include Kinetic energy which is associated with the movement of bodies. Potential energy which is stored by virtue of a body's position relative to its surface is also called gravitational potential energy.
Thermal Energy or Heat can be defined as the energy associated with the kinetic energy of the molecules that make up an element, it can be manifested if there is a temperature difference between two bodies.
Chemical energy released or formed from chemical reactions, Solar energy from sunlight. This form of energy is used to generate electricity through photovoltaic plates, for example.

What do biologists call the specialized cells in the nervous system that detect heat, pressure, and other environmental stimuli? A. first responders B. mitochondria C. receptors D. organelles
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.
What are receptors?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: 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.
What shows the low light in the evening?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.
