How can changes on earths surface affect changes below surface

Answers

Answer 1

Answer:

There are several changes that occur on the earth's surface but also affects the changes below the surface, some of them are as follows:

When rainfall occur on the sandy surface on earth, it looses the soil under the surface and can cause landslides.Imbalance in the food chain above or on the earth surface can affect the nutrient quantity below the surface that is essential for soil bacteria and other microorganisms.Deforestation can also loosen the soil and soil under surface can shift its position.Use of chemicals on agriculture surface can lead to change the fertility of soil below the surface.

Which of the following is a human-related release of greenhouse gases?
O A. Wild animal respiration
OB. Volcanic eruptions
O C. Intensive agriculture
O D. Solar cycles
It’s A

Answers

Answer:

C

Explanation:

I'm pretty sure it's actually C and not A. It's asking for human-related release from greenhouse gases. Humans don't cause volcanic eruptions and aren't in control of wildlife's respirations. The solar cycles has to do with the magnetic flux that rises to the surface of the sun and lasts 11 years. Intensive agriculture increases pollution which harms the environment.

Autosomal dominant and recessive: Autosomal dominant states a pattern of inheritance in which an individual carries one normal gene and one copy of a mutant gene while autosomal recessive states a pattern of inheritance in which an individual have two copies of the mutant gene.

Incomplete dominance:  Incomplete dominance states a heterozygous condition in which both the alleles present are partially expressed and produces intermediate phenotype.

Codominance: In codominance and individuals receive alleles, if both the alleles are different including dominant and recessive, dominant allele will be expressed while recessive will be masked.

Multiple alleles: organisms with multiple alleles exist with two copies of every gene present in a population with variation in genes.

Sex linked gene: In humans and some other organisms, sex linked genes are influenced by genes on the X chromosome. for example: If a gene is present on the X chromosome only and not the Y chromosome.

Which of the following statements best describes the role of hormones in the body? Hormones send chemical signals throughout the body to regulate body processes.

Answers

Answer:

Hormone production and release are primarily controlled by negative feedback. In negative feedback systems, a stimulus elicits the release of a substance; once the substance reaches a certain level, it sends a signal that stops further release of the substance. In this way, the concentration of hormones in blood is maintained within a narrow range. For example, the anterior pituitary signals the thyroid to release thyroid hormones. Increasing levels of these hormones in the blood then give feedback to the hypothalamus and anterior pituitary to inhibit further signaling to the thyroid gland, as illustrated in Figure 18.14. There are three mechanisms by which endocrine glands are stimulated to synthesize and release hormones: humoral stimuli, hormonal stimuli, and neural stimuli.

Explanation:

Hyperthyroidism is a condition in which the thyroid gland is overactive. Hypothyroidism is a condition in which the thyroid gland is underactive. Which of the conditions are the following two patients most likely to have?

Patient A has symptoms including weight gain, cold sensitivity, low heart rate and fatigue.

Patient B has symptoms including weight loss, profuse sweating, increased heart rate and difficulty sleeping.Humoral Stimuli

The term “humoral” is derived from the term “humor,” which refers to bodily fluids such as blood. A humoral stimulus refers to the control of hormone release in response to changes in extracellular fluids such as blood or the ion concentration in the blood. For example, a rise in blood glucose levels triggers the pancreatic release of insulin. Insulin causes blood glucose levels to drop, which signals the pancreas to stop producing insulin in a negative feedback loop.

Hormonal stimuli refers to the release of a hormone in response to another hormone. A number of endocrine glands release hormones when stimulated by hormones released by other endocrine glands. For example, the hypothalamus produces hormones that stimulate the anterior portion of the pituitary gland. The anterior pituitary in turn releases hormones that regulate hormone production by other endocrine glands. The anterior pituitary releases the thyroid-stimulating hormone, which then stimulates the thyroid gland to produce the hormones T3 and T4. As blood concentrations of T3 and T4 rise, they inhibit both the pituitary and the hypothalamus in a negative feedback loop.

The statement that describes the role of hormones in the body is Enzymes reduce the activation energies of biological reactions.

What are hormones?

Hormones are chemicals that are secreted by the two glands, endocrine and exocrine glands.

Endocrine glands secrete hormone directly into the bloodstream, and exocrine glands are secrete hormones into ducts.

New mutations can also occur randomly, so there’s a chance that children of parents who didn’t inherit the gene for Huntington’s can develop a mutation in the gene that causes Huntington’s disease explain how protein synthesis contributes to the symptoms of the disease

Answers

Answer:

It depends on the mutation rate  

Explanation:

Mutations are genetic changes that occur naturally by errors during DNA replication which are not repaired by the DNA repair mechanisms. When a mutation occurs in the germline line, it may pass to the next generations and thus perpetuate itself. Huntington's disorder is an autosomal dominant disorder associated with a trinucleotide repeat mutation in the huntingtin (HTT) gene localized on chromosome 4, which encodes the Huntingtin protein. It has been shown that the high levels of Huntingtin are linked to Huntington's disorder, thereby it is believed that this mutation might be associated with a higher expression of the HTT gene.

How do the products of meiosis compare to the original cell?

You didn't put the answer options, but the frog life cycle phases are:

Mating: In this phase two adult frogs, a male and a female, mate in the water or on plates. At this point, the male frog wraps his arms around the female and overlaps over her back. Spawning: At this point, the female releases the eggs into the water, ready to be fertilized by the males. Fertilization occurs outside the female's body. Eggs: Some fertilized eggs will be devoured by small animals, but those that survive will hatch 7-9 days after fertilization, releasing a frog shape, called a tadpole.Tadpole: It is similar to a fish and is formed by tail, mouth and gills. After 7 days of life, you will be able to swim and feed on algae. Four weeks later he will develop teeth and skin. When he reaches 9 weeks he will begin to change his shape, growing in size and developing head and legs. At that moment it will look more like a frog, but it still has a long tail. Metamorphosis of the fish: Up to twelve weeks of age it will reach the shape of a frog and start to feed on insects. Gradually it will lose its tail and its tongue will grow. The 16 weeks will become an adult frog, being able to mate and restart the cycle.

a) Name the 3 types of solutions taking inference from the picture above and explain the process taking place in A
b) When plant cell is placed in solution C, which part prevents it from bursting and how?
c) Name the process by which Amoeba obtains its food

Answers

This diagram shows vegetal and animal cells placed in solutions of different concentrations.

a)Solution A is called hypertonic because it has a higher concentration than the cell's cytoplasm. In the animal cell, it causes the water to diffuse out through osmosis. In the plant cell water is lost through the same process but the cell wall remains intact while the membrane reduces in volume.

Solution B is called isotonic because it has around the same concentration as the cytoplasm of the cell. It does not influence the volume of the cell.

Solution C is called hypotonic because it has a lower concentration than the cytoplasm. In the animal cell, it causes the cell to fill with water until it bursts(this process is called cytolysis). In the plant cell water diffuses through the membrane, but the cell doesn't burst.

b)Plant cells have a strong cell wall made of cellulose, hemicellulose and, lignin that prevents cytolysis.

c)Amoeba obtains its food through a process called phagocytosis in which the solid material is engulfed in a vesicle that enters the cell.

Plant cells have a strong cell wall made of cellulose, hemicellulose and, lignin that prevents cytolysis.

What do you mean by cytolysis?

Cytolysis, or osmotic lysis, occurs when a cell bursts due to an osmotic imbalance that has caused excess water to diffuse into the cell. Water can enter the cell by diffusion through the cell membrane or through selective membrane.

Cytolysis or osmotic lysis occurs in animal cells and certain bacteria, especially when the cells are exposed to a hypotonic environment, causing the water to move into the cell, thereby increasing or expanding the cell.

When cells burst and die, their contents are released, causing inflammation. Every day, more than 50 billion cells die in our bodies. These are not random events, but part of a finely tuned biological mechanism called programmed cell death.

Interneurons relay the impulse to motor neurons in the spinal cord.She immediately moves her foot. The sensory neuron generates an impulse. Receptors in her toe receive stimuli. Motor neurons signal the leg muscles.

Answer:

4. Receptors in her toe receive stimuli

3. The sensory neuron generates an impulse.  

1. Interneurons relay the impulse to motor neurons in the spinal cord.

5. Motor neuron signal the leg muscles    

2. She immediately moves her foot.  

Explanation:

The reflex arc refers to an action mechanism that responds to different stimuli.  It is an involuntary reaction involving different nervous vias. The reflex arc is composed of receptors, afferent nervous fibers, efferent nervous fibers, and effectors.    

Receptors are located in nervous terminals and are widely distributed in the organism. Receptors are capable of receiving stimuli from different nature, and most of them are specialized in one kind of stimuli such as vision, audition, touch, among others. In the exposed example, these sensory receptors were located in the toe, and probably they were touch receptors.

When they receive the stimulus the sensory neuron transforms it into an excitatory nervous impulse that goes to the central nervous system along the afferent nerves. This stage is known as the afferent via, beginning with the environmental information received by sensory receptors, and ending in the arrival of the transcripted message to the central nervous system.

When the central nervous system receives the information, it processes it and sends an appropriate answer according to the stimulus. The message goes along the interneurons to the motor fibers, which are in charge of taking that answer to its destiny, the effectors. Effectors are usually muscles or glands, and they transform the received impulse into a motor answer that executes the reflex action. In the exposed example, the effector in the muscle. This stage is known as the efferent via, beginning in the central nervous system sending an answer impulse and ending in the effector (muscle) executing the answer.

In the microarray analysis some genes, such as ERB-B2 and ESR1, have been found to be associated with particular disease or conditions such as cancer. Other genes, such as the ABC-B2 gene, are not associated with a disease but are involved in resistance to certain drugs or treatments. Why would it be useful to test for the expression of genes like the ABC-B2 gene on the microarray

Answers

Answer:

The expression of genes associated with drug resistance leads to the reduction in the effectiveness of drugs against cancer cells.

Explanation:

In cancer, drug resistance is produced when oncogenic cells are able to develop mechanisms of resistance against drugs such as, for example, chemotherapeutic agents. In these cases, therapeutic treatments become ineffective to fight against cancer cells and tumor progression. In consequence, it is imperative to trace the expression of target oncogenes associated with drug resistance in order to provide effective treatments to eliminate cancer cells.
