Sand for beaches comes from rocks in the area that are weathered down, and
their sediment is deposited in the area beaches. The beaches are then eroded,
and the sediment is moved away from the beaches. If rocks stopped weathering,
how would the beach change?
Answers
Answer:
Beaches would shrink until they were no longer there because the sediment is pulled away from the shores by the tide and there would be no new rock sediment to replace the old rock sediment.

Explanation:
What are the organs of the immune system?
Publication Details
Our immune system is made up of both individual cells and proteins as well as entire organs and organ systems. The organs of the immune system include skin and mucous membranes, and the organs of the lymphatic system too.
Organs that function as barriers
Your skin and mucous membranes are the first line of defense against germs entering from outside the body. They act as a physical barrier with support from the following:
Antibacterial substances can kill germs right from the start. A certain enzyme found in saliva, the airways and tear fluid destroys the cell walls of bacteria.
Mucus in the bronchi helps trap many of the germs we breathe in so they can be moved out of the airways by hair-like structures called cilia.
Stomach acid stops most of the germs that enter the body in the food we eat.
Harmless bacteria on our skin and many of the mucous membranes in our body also act as part of the immune system.
In addition, the reflexes that cause us to cough and sneeze help to free our airways of germs.
Illustration: The parts of the immune system
The parts of the immune system
Lymphoid organs
The lymphatic system is composed of:
Primary lymphoid organs: These organs include the bone marrow and the thymus. They create special immune system cells called lymphocytes.
Secondary lymphoid organs: These organs include the lymph nodes, the spleen, the tonsils and certain tissue in various mucous membrane layers in the body (for instance in the bowel). It is in these organs where the cells of the immune system do their actual job of fighting off germs and foreign substances.
Bone marrow
Bone marrow is a sponge-like tissue found inside the bones. That is where most immune system cells are produced and then also multiply. These cells move to other organs and tissues through the blood. At birth, many bones contain red bone marrow, which actively creates immune system cells. Over the course of our life, more and more red bone marrow turns into fatty tissue. In adulthood, only a few of our bones still contain red bone marrow, including the ribs, breastbone and the pelvis.
Thymus
The thymus is located behind the breastbone above the heart. This gland-like organ reaches full maturity only in children, and is then slowly transformed to fatty tissue. Special types of immune system cells called thymus cell lymphocytes (T cells) mature in the thymus. Among other tasks, these cells coordinate the processes of the innate and adaptive immune systems. T cells move through the body and constantly monitor the surfaces of all cells for changes.
Lymph nodes
Lymph nodes are small bean-shaped tissues found along the lymphatic vessels. The lymph nodes act as filters. Various immune system cells trap germs in the lymph nodes and activate the creation of special antibodies in the blood. Swollen or painful lymph nodes are a sign that the immune system is active, for example to fight an infection.
Spleen
The spleen is located in the left upper abdomen, beneath the diaphragm, and is responsible for different kinds of jobs:
It stores various immune system cells. When needed, they move through the blood to other organs. Scavenger cells (phagocytes) in the spleen act as a filter for germs that get into the bloodstream.
It breaks down red blood cells (erythrocytes).
It stores and breaks down platelets (thrombocytes), which are responsible for the clotting of blood, among other things.
There is always a lot of blood flowing through the spleen tissue. At the same time this tissue is very soft. In the event of severe injury, for example in an accident, the spleen may rupture easily. Surgery is then usually necessary because otherwise there is a danger of bleeding to death. If the spleen needs to be removed completely, other immune system organs can carry out its roles.

A freckled man marries a woman without freckles. They have four children, two with freckles, and two without freckles. What are the genotypes of all these people?
Answers
Answer:
The genotype of the father: Ff
The genotype of the mother: ff
The genotype of the two children without freckles: ff
The genotype of the two children with freckles: Ff
Explanation:
Freckles (F) are is dominant trait, so one dominant allele in the genotype of an individual will cause he/she to have freckles. Since the father has freckles, but only two of his children has freckles; that means that he has a heterozygous genotype. In the Punnett Square, the offsprings' genotypes are shown, as well as the parents'.
A freckled man marries a woman without freckles, and they have four children, two with freckles and two without, so the genotype of the parents are Ff, ff and the children with freckles are Ff, while the freckleless are ff types.
What is the significance of the freckle trait?There are both dominant and recessive traits that determine the person's quality, such as freckles, which are dominant over being freckleless. When the parents with freckles cross with the parents without freckles, they will produce half the freckles and half the freckleless. The parent with a freckle is heterozygous (Ff), so two types of gametes will be produced, such as F and f, and will form Ff and ff offspring when crossed with the freckleless parent (ff).
Hence, a freckled man marries a woman without freckles, and they have four children, two with freckles and two without, so the genotype of the parents are Ff, ff and the children with freckles are Ff, while the freckleless are ff types.

Explanation:
Darwin's Theory of Evolution by Natural Selection
More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.Charles Darwin's theory of evolution states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. ... As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve.

Question 23 (6 points)
Sea Urchins are aquatic mammals that dive down to catch and eat sea urchins. Sea
urchins hunt the sea floor to catch and eat starfish. Starfish feed off of kelp forests
under the sea.
When sea otters overpopulate they clean out the sea urchins very quickly. This
allows the starfish to overpopulate and eat too much of the kelp forests.
Answer the following questions for 2 points each:
1. Name the TWO organisms that act as Carnivores in the ecosystem described
above.
2. Identify the ecological roles of the other TWO organisms.
3. Identify which of the four organisms above would be considered a keystone
species. Explain why.
Answers
Answer: 1. Sea urchins and sea otters
2. They are prey for carnivores.
3. Sea otters, star fish
Explanation:
Sea urchins and sea otters are carnivores as they eat on the flesh of starfish and sea urchins respectively.
Starfish feed on the kelp forests which are the producers in the food chain and the starfish is the primary consumer and prey for sea urchins. So, starfish and kelp forests are the prey in the marine ecosystem.
Keystone species is the one which controls the population of other inferior species in an ecosystem. Here, sea otters consume sea urchins so the population of sea urchins remained in control Starfish controls the population of kelp forest.

In the disease myasthenia gravis, the human body makes-by mistake- antibodies to its own acetylcholine receptor molecules. These antibodies bind to and inactivate acetylcholine receptors on the plasma membrane of muscle cells. The disease leads to devastating progressive weakening of the muscles of people affected. Early on, they may have difficulty opening their eyelids, for example, and, in an animal model of the disease, rabbits have difficulty holding their ears up. As the disease progresses, most muscles weaken, and people with myasthenia gravis have difficulty speaking and swallowing. Eventually, impaired breathing can cause death. Explain which step of muscle function is affected
Answers
Answer:
Muscle contraction function.
Explanation:
The nerve endings possess synaptic acetylcholine vesicles ready to be released. The action potential depolarizes the presynaptic terminal and increases the concentration of axoplasmic calcium; Acetylcholine molecules are thus released, so that the concentration of the neurotransmitter at postsynaptic (nicotinic) receptors is temporarily increased. This is followed by post-synaptic membrane depolarization, muscle membrane action potential with increased rnioplasmic calcium concentration, and finally muscle contraction. Acetylcholine is hydrolyzed by acetylcholinesterase and resynaptic at the presynaptic level by cholinecetyltransferase. The etiopathogenesis of myasthenia gravis is autoimmune and there are antibodies against acetylcholine receptors that circulate in the blood, as well as a decrease in the number of receptors on the motor plates, that is, it is produced by the postsynaptic blockage of the myoneural plaque, that generates fatigue and localized or generalized muscle weakness that is characterized by the worsening of the contractile force of the muscle.

RNA interference is a mechanism of eukaryotic gene regulation. In this mechanism, the enzyme “dicer” cuts dsRNA into smaller fragments called siRNA, which form a complex with RISC and degrade specific RNA.
siRNA or small interfering RNA as a part of RISC complex finds and binds to complementary mRNA and it induces the cleavage of mRNA. This causes degradation of that mRNA. This is the way RNA interference prevents translation.

Answers
Answer:
B. the two strands of DNA are antiparallel, and DNA polymerase can only add new nucleotides onto a 5' end
Explanation:
Deoxyribonucleic acid, known as DNA, is the genetic material of a cell, which must first undergo replication i.e produce two identical copies of itself, before a cell can divide. During replication, the double stranded DNA unwinds into a replication fork consisting of two single strands of DNA.
These single strands of DNA are called leading strand (runs from 3'-5') and lagging strand (runs from 5'-3'). These single strands that runs at opposite direction from one another exists at the replication fork because the two strands of DNA are antiparallel i.e. are opposite to one another, and DNA polymerase can only add new nucleotides onto a 5' end.
Leading and lagging DNA strands exist at a replication fork because the two strands of DNA are antiparallel, and DNA polymerase can only add new nucleotides onto a 5 'end.
A replication fork is the juncture between two strands of DNA when it is replicating itself.
In each of them (speaking of the homologous strands) the opposite chain is carried out to have the double genetic information when approaching cell division.
The direction in which the enzymes act is unique from 5 'to 3', this determines the template chain must have the direction 3'→ 5', so that the new chain in formation, complementary and antiparallel, has the direction 5 '→ 3' coinciding with the enzyme's working system.The basic reaction that takes place in replication is a polymerization reaction, in a growing DNA chain a nucleotide is incorporated whose base is complementary to that of the template chain.The DNA polymerases at the two ends of the free nucleotide to be incorporated use its phosphate group or 5 'end to add it to the growing chain.Therefore, we can conclude that leading and lagging DNA strands exist at a replication fork because the two strands of DNA are antiparallel, and DNA polymerase can only add new nucleotides onto a 5 'end.
