Read this paragraph from "How Water Loss Affects Biodiversity."
“When a region experiences a significant drought, many animals may die from lack of water and food. […] If tourism declines due to high wildlife casualties, then the locals who depend on income from tourism will lose their livelihood. People may then turn to farming to earn money, but crops require water to grow. This can place further strain on the water supply and worsen the original problem of the drought.”
What event can cause many animals to die from lack of water and food?
Answer:
Eggs and fried chicken with mentally stabled fries
what is the specific function of the structure labeled f?
Answer:
The muscle spindle indicated by F functions as a proprioceptor that is responsive to changes in the length of the surrounding muscle.
Explanation:
The specific function of the structure labeled f is proprioceptor that is responsive to changes in the length of the surrounding muscle.
What is the function of the muscle spindle?The muscle spindle is activated whenever the weight of the body, tending to bend the knees, stretches the muscles. Stimuli are sent to the spinal cord and through the motor nerve and the muscles contract to counteract the action of gravity.
The Muscle spindle is a proprioceptive sensory receptor spindle composed of muscle bundle fibers. Its main function is to signal changes in the length of the muscle on which it is located. Muscle Spindles are structures responsible for mechanical myo-integrity and regulation of muscle contraction/distension.

Bob has brown hair and Sally has blonde hair. If brown hair is dominant and blonde hair is recessive, is it possible for Bob and Sally to have a blonde-haired child? Use the GENOTYPE of each parent to EXPLAIN your answer.
Answer:
Yes, it is possible.
Explanation:
Bob could either be h.o.m.ozygous (BB) for brown hair or h.e.terozygous (Bb) for brown hair. If Bob is h.e.t.erozygous for brown hair, this means he has a blonde hair allele. For a child to be blonde, the child needs one blonde allele from each parent and this is possible if Bob has a blonde hair allele. However, it is not possible if Bob is h.o.m.ozygous for brown hair.
In the image, there is a punnet square showing the possible genotypes of the children if Bob is h.e.t.erozygous for brown hair.
how how does absorption of materials play a role in diffusion
The combined processes of absorption and diffusion are very necessary in the process of digestion.
The combined processes of absorption and diffusion are very necessary in the process of digestion especially in the intestines. The process by which nutrients enter the blood from the intestines is diffusion.
Diffusion occurs when the nutrients must have been absorbed into the blood from the intestines.

Which mechanism allows lipid-soluble substances to move through the membranes of endothelial cells of capillaries
Answer:
Diffusion.
Explanation:
The mechanism that allows lipid-soluble substances to move through the membranes of endothelial cells of capillaries is simple diffusion.
Simple diffusion is a passive transport mechanism that allows lipid-soluble substances to move across the membranes of endothelial cells in capillaries. This process occurs down a concentration gradient, from an area of higher concentration to an area of lower concentration, without the need for energy expenditure.
The membranes of endothelial cells, which make up the walls of capillaries, are composed of a lipid bilayer. Lipid-soluble substances, such as oxygen, carbon dioxide, steroid hormones, and certain lipid-soluble drugs, can readily diffuse through this lipid bilayer due to their ability to dissolve in and pass through the hydrophobic interior of the membrane.
Unlike lipid-soluble substances, water-soluble substances, such as ions and polar molecules, are unable to passively diffuse through the lipid bilayer. Instead, they rely on specific transport mechanisms such as facilitated diffusion or active transport to cross the endothelial cell membrane.
In the context of capillaries, simple diffusion allows lipid-soluble substances to move from the bloodstream through the endothelial cell membranes and into surrounding tissues or vice versa. This process plays a crucial role in the exchange of gases, nutrients, and waste products between the bloodstream and the tissues.
It is important to note that while simple diffusion allows for the passage of lipid-soluble substances, the movement of these substances can also be influenced by factors such as concentration gradients, molecular size, solubility, and the presence of transport proteins. However, the primary mechanism by which lipid-soluble substances traverse the endothelial cell membranes of capillaries is through simple diffusion.

How does carbon atom work on plants
Answer: Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.This energy makes carbon molecules an excellent source of fuel for all living things. During photosynthesis, plants absorb carbon dioxide and sunlight to create fuel glucose and other sugars for building plant structures. This process forms the foundation of the fast (biological) carbon cycle.

C 90-degrees W longitude
D International Date Line
The Equator line does not pass through the north and south poles. This line divides the Earth's planet into two hemispheres.
The Equator can be defined as an invisible line located at the center of the Earth (0 degrees latitude).
This invisible line (Equator) divides the Earth into two hemispheres: the northern hemisphere and the southern hemisphere.
The Equator is a circle of latitude, and the distance of this imaginary line is approximately 40,000 km in circumference.

D) There are a total of four hydrogen atoms
E) There are two total atoms present hydrogen and oxygen
Examine the chemical formula shown here there are three total atoms two of which are hydrogen and one of which is oxygen and this chemical formula can be seen in the process of photosynthesis also.
What is photosynthesis?The process of photosynthesis has been defined as the process in which green plants prepare their own food in the presence of sunlight and during this process heat energy has been converted into the chemical energy and this process has been taken place in the green plant only.
Photosynthesis has the process through which plant cells use carbon dioxide & water to create oxygen & energy rich organic compounds. They do so by converting sunlight ie light energy into chemical energy. This is possible due to presence of chlorophyll in them. Animals can't do so, as they dont have chlorophyll.
