Explain what happens to muscle force production at extremes of length

Answers

Answer 1
The sarcomere is the basic unit of a striated muscle and the force of a muscle is directly related to the extension that the sarcomere is under. When a sarcomere is extended from 1.5 micrometres to about 3 micrometres, the muscles' force is great and max at about 2/2.5 micrometres. When the muscle is fully extended and, therefore, the sarcomere is extended over than 3 micrometres, the muscle force decreases exponentially.

Part a - the cell cycle drag the pink labels onto the pink targets to identify the two main phases of the cell cycle. then drag the blue labels onto the blue targets to identify the key stages that occur during those phases.

Answers

The cell cycle has two main phases which is marked pink. These are called the interphase and m-phase. The interphase has three key stages which are gap 1, s phase and gap 2. S phase will be marked with blue because it is an important phase wherein DNA replication occurs. And the M-phase is where the cell itself divides with an equal amount of chromosomes and a new daughter cell is generated.

The two main stages of the cell cycle are interphase and M phase. Interphase is further segregated into G1, S, and G2 phase while the M phase is segregated into prophase, metaphase, anaphase, and telophase.

Further Explanation:

The cell cycle refers to an ordered flow of events which includes cell growth as well as cellular division. This cycle produces 2 new daughter cells. The cycle starts with interphase; during which, the cell grows and replicates its own DNA or deoxyribonucleic acid. The interphase begins with:

1. G1 phase: This is the primary growth phase provide nutrient to the cell.

2. S phase or synthesis of DNA: During this phase, the replication of DNA takes place. The centrosome is divide and forms mitotic spindle during the mitosis phase.

3. G2 or second gap: during this phase, the cell mainly replenishes its energy stores as well as synthesizes the proteins which are required for the chromosome manipulation.

The second phase of the cell cycle is the mitosis or M phase. Mitotic phase refers to a multiphase process during which the chromosomes are aligned, segregated, and moved into the 2 new daughter cells which are identical to each other.

This phase starts with:

1. Prophase: During this phase, the condensation of the chromosomes takes place and these chromosomes become visible. Spindle fibers formation take place, breakdown of the nuclear envelope, and nucleolus disappear.

2. Metaphase: During this phase, the formation of spindle fibers is completed and centrosomes are found at the opposite terminals of the cell. The chromosomes line up at the metaphase plate. Each of the sister chromatids is linked to the spindle fiber starting from the opposite poles.

3. Anaphase: During this phase, the cohesion proteins link with the sister chromatids and splits them down. The sister chromatids are pulled towards the opposite terminals of the cell and the non-kinetochore spindle fibers mainly lengthen and elongate the cell.

4. Telophase: During this last phase, the chromosomes arrive at the opposite terminals and start to decondense. Nuclear envelope reappears, and mitotic spindle breaks down. This marks the end of the mitosis.

The end phase of the cell cycle is called cytokinesis wherein the cleavage furrow occurs are segregates the daughter cells. In plant cells, the cell plate is responsible for the segregation of the daughter cells.

Answers

First one: Anaerobic, oxygen.
Second one: aerobic 
Third one: fermentation.
Fourth one: CO₂ 
Fifth: 34-38 ATP, 2 ATP 

The term anaerobic describes cellular respiration in the absence of oxygen. Oxygen is the final electron acceptor in aerobic respiration.

What is respiration?

Respiration is the process of releasing energy from food through oxidation. Aerobic along with anaerobic respiration are the two kinds of respiration.

Aerobic means "with air," and it refers to the body's use of oxygen to produce energy. This usually refers to any exercise that lasts more than two minutes.

Aerobic 'steady state' exercise is performed continuously. Anaerobic refers to the body producing energy without the use of oxygen.

The term anaerobic refers to cellular respiration that occurs in the absence of oxygen. In aerobic respiration, oxygen is the final electron acceptor.

Fermentation is the breakdown of organic molecules in the absence of oxygen. Yeast converts pyruvate to carbon dioxide and acetaldehyde during fermentation.

Aerobic respiration generates 34-38 ATP molecules, whereas anaerobic respiration generates only two.

What were the common causes and risk factors found between the majority of the skin disorders?

Answers

Skin is the first line of defense mechanism of our immune system. It acts as a barrier for pathogenic and opportunistic microorganisms. However, skin itself has a microbiota that does not allow other microorganisms to invade or colonize. Any wound, cut or change in the pH of skin due to environmental conditions or any disease might lead to the entry of the opportunistic microorganisms inside the skin. This leads to several skin disorders such as dermatitis, eczema, cellulitis, warts, etc. Thus, it is extremely important to keep the skin hydrated and healthy to avoid any kind of microbial invasion.

Carbon enters the soil when humans perform respiration and exhale it. /D. Carbon enters the soil when plants make glucose and deposit it into the soil.
whats the answer A/B/C OR /D

Answers

A. /Carbon enters the soil when decomposers produce it.

 

Carbon is deposited into the soil through decomposers which digests and generate carbon when organisms die and become buried beneath the soil. This process also is observed during the carbon cycle. Carbon cycle is a biogeochemical cycle where the transfer of carbon from the different spheres of the earth occurs. This involves the geosphere, hydrosphere, atmosphere, pedosphere and most especially, the biosphere. 

Final answer:

Carbon enters the soil when plants make glucose and deposit it into the soil.

Explanation:

The correct statement that explains how carbon enters the soil during the carbon cycle is Option D. Carbon enters the soil when plants make glucose and deposit it into the soil. During photosynthesis, plants convert carbon dioxide from the atmosphere into glucose, which is then used for growth or stored in the roots and leaves. As plants decay or are consumed by decomposers, the carbon is released back into the soil as organic matter.

Which area of the limbic system has considerable influence on the secretion of hormones throughout the body?

Answers

The hypothalamus.

The hypothalamus  links the nervous system with the endocrine system.  It's part of the limbic system but can also synthesizes and secretes  hypothalamic hormones. These hormones will either stimulate or inhibit the pituitary gland, which releases hormones that go throughout the body to the glands and organs.

 



Hypothalamus is the part of the limbic system that has considerable influence on the secretion of hormones throughout the body.

Further Explanation:

The parts of the brain that are located under the temporal lobe sandwiching the thalamus collectively constitute the limbic system. The limbic system was first defined by Paul D. MacLean. The biggest area of the brain is occupied by the forebrain. The limbic system, the hypothalamus, thalamus, and the pineal gland are the structures of the forebrain.  A tiny structure in the brain that is present just on the brain stem in between the cerebral cortex and midbrain is called the thalamus.

The part of the forebrain that lies beneath the thalamus is known as the hypothalamus. Hypothalamus means "under the thalamus" This part of the brain is responsible for the control and coordination of the autonomous nervous system, the pituitary gland secretion, the thirst, temperature and systems of homeostasis.

Two different sets of nerve cells that are present in the hypothalamus stimulates the production of the hormones. The maintenance of proper production of all the hormones is done by the gland. One set of the nerve cells transports the hormones produced by hypothalamus to the pituitary stalk from where the hormone is transported to the posterior lobe of the pituitary gland. These hormones (ADH and oxytocin) are then released in the bloodstream.
