Explanation:
Dendrites receive nerve impulses from other cells.
Hope it help..The right answer is B. Dendrites receive nerve impulses.
What are Dendrites ?Dendrites are specialized structures on neurons that receive signals, or impulses, from other neurons or from sensory receptors in the environment. These signals can be either electrical or chemical, and they are transmitted across synapses, which are tiny gaps between neurons or between neurons and effector cells, such as muscles or glands.
Dendrites play a crucial role in the transmission and processing of these signals. They are covered in tiny protrusions called dendritic spines, which increase the surface area of the dendrite and allow for a greater number of synapses to be formed with other neurons. This increased connectivity enables the dendrite to receive and integrate signals from multiple sources and to process them in a highly sophisticated way.
Once the signals are received, they are transmitted to the cell body of the neuron, where they are integrated and processed before being transmitted along the axon of the neuron. The axon is a long, slender extension of the neuron that carries the electrical impulses from the cell body to the axon terminals, which are specialized structures that form synapses with other neurons or with effector cells.
In summary, dendrites are specialized structures on neurons that receive signals from other neurons or sensory receptors, and they play a key role in integrating and processing these signals before transmitting them to the cell body of the neuron. This allows the neuron to perform complex computations and respond to the environment in a highly sophisticated way.

describe the structure and functions of various organelles in a mature animal cell
Answer:
Explanation:
Cell Membrane
A thin semipermeable membrane layer of protein and fats surrounding the cell. Its primary role is to protect the cell from its surrounding. Also, it controls the entry and exit of nutrients and other microscopic entities into the cell.
Nuclear Membrane
It is a double-membrane structure that surrounds the nucleus. It is also referred to as the nuclear envelope.
Nucleus
It is an organelle that contains several other sub-organelles such as nucleolus, nucleosomes and chromatins. It also contains DNA and other genetic materials.
Centrosome
It is a small organelle found near to the nucleus which has a thick centre with radiating tubules. The centrosomes are where microtubules are produced.
Lysosome (Cell Vesicles)
They are round organelles surrounded by a membrane and comprising digestive enzymes which help in digestion, excretion and in the cell renewal process.
Cytoplasm
A jelly-like material which contains all the cell organelles, enclosed within the cell membrane. The substance found within the cell nucleus, contained by the nuclear membrane is called the nucleoplasm.
Golgi Apparatus
A flat, smooth layered, sac-like organelle which is located near the nucleus and involved in manufacturing, storing, packing and transporting the particles throughout the cell.

Just a quick summary will do!:
A. Sickle Cell Anemia is caused by a base change in DNA. Describe how the base change results in a faulty protein being made.
B. Briefly explain the inheritance pattern of the condition.
Answer: a) The single base change mutation occurs at the beta chain of haemoglobin when glutamic acid is replaced with valine.
b) Sickle Cell Anemia is inherited in an autosomal recessive pattern.
Explanation:
Haemoglobin is a protein found in the red blood cells whose main function is to transport oxygen. Sickle Cell Anemia is a disorder caused by a base change in DNA beta chain of haemoglobin. The amino acid valine is substituted for glutamic acid at one point in each of the two beta chains. When this type of hemoglobin is exposed to low oxygen, it forms elongated crystals inside the red blood cells that are sometimes 15 micrometers in length. These make it almost impossible for the cell to pass through many small capillaries, and the spiked ends of the crystals are likely to rupture the cell membrane, leading to sickle cell anemia.
In describing the inheritance patterns of sickle cell anaemia, it is of autosomal recessive pattern. This means that the parent of the affected individual both carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition. The gene for normal red blood cell is dominant over the gene for abnormal red blood cell which is said to be recessive. A person who is a stickler should have the genotype SS.

how does the Digestive system help maintain homeostasis?
In your answer, include the most important organ(s) (list at least 2) and include what they do to make the system work. It must include at least 3 full sentences
Answer:
The bacterial flora in the intestines are essential to homeostasis in the body, they not only break down food so the nutrients can be absorbed, they produce vitamins like biotin and vitamin K and guard against harmful bacteria that enter the system. While your heart is a vital organ, the brain (and the nervous system that attaches to the brain) make up the most critical organ system in the human body. The digestive system ordinarily gets 20% to 25% of the oxygenated blood pumped out by the heart and the receptors in muscles provide the brain with information about body position and movement, the brain controls the contraction of skeletal muscle the nervous system regulates the speed at which food moves through the digestive tract.

Achromoplast stores while a leucoplast stores A. starch; pigments B. chlorophyll; starch C. pigments; chlorophyll D. pigments; starch
Answer:
D. pigments; starch.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles.
A chromoplast can be defined as a heterogeneous organelle or plastids that is typically responsible for pigment synthesis and their storage in a plant. The pigments include red, orange, yellow or chlorophyll.
On the other hand, leucoplast is a colorless plastid i.e plastic lacking photosynthetic pigments that are typically found in storage organs, underground stems, cotelydons, roots, tubers, seeds, or endosperm etc., used for the storage of starch in the absence of sunlight.
Hence, a chromoplast stores pigments while a leucoplast stores starch.

what caused a decrease of carbon dioxide in the biodomes air
Answer:
As organisms release energy during cellular respiration, carbon dioxide is produced from the carbon in energy storage molecules. ... Carbon dioxide in the biodome decreased because decomposers decreased which means there was a decrease in cellular respiration overall.
There are several possible reasons why the carbon dioxide levels in the air of a biodome might decrease like photosynthesis, respiration, ventilation and carbon sequestration.
What are the factors responsible for decrease of carbon dioxide in the biodomes air?There are several possible reasons why the carbon dioxide levels in the air of a biodome might decrease. Some possible causes include:
Photosynthesis: If the biodome contains plants, they may be using carbon dioxide during photosynthesis to produce oxygen and glucose. This process would remove carbon dioxide from the air.
Respiration: If the biodome contains animals or microorganisms that respire, they may be consuming oxygen and producing carbon dioxide. This would result in a decrease in carbon dioxide levels in the air.
Ventilation: If the biodome has a ventilation system, it may be designed to remove excess carbon dioxide from the air. This could result in a decrease in carbon dioxide levels.
Carbon sequestration: If the biodome has systems in place to capture and store carbon dioxide, such as through the use of plants or other methods, this could result in a decrease in carbon dioxide levels in the air.
It's important to note that the specific cause of a decrease in carbon dioxide levels in the biodome's air will depend on the specific conditions and systems in place within the biodome.
