Answer:

Bones are organs composed of hard living tissue providing structural support to the body – it's scaffolding. It is a hard matrix of calcium salts deposited around protein fibers. Minerals make bone rigid and proteins (collagen) provide strength and elasticity. ... The outer layer of bone is called Cortical bone.

Answer:

Organisms use carbohydrates produced by photosynthesis by oxidizing them to produce energy for respiration. - The glucose produced in green plants is directly utilized for respiration and other activities, while the excess is stored in the form of starch.

Answer:

A single bout of resistance exercise training increases muscle protein synthesis by as much as 120-150% above resting levels

Answer:

20 Calories

Explanation:

If a food product is labeled to contain 20 calories, it likely contains the number of calories. Keep in mind, these labels can be inaccurate.

Birds that detect UV light have favorable characteristics that enable them to survive and reproduce. These  characteristics are passed on to their offspring.

According to Darwin's theory of evolution, organisms that are better adapted to their environment live long enough to survive and reproduce and pass on these favorable traits to their offspring.

Since birds depend on these fruits for food and these fruits reflect UV light. A bird that can not detect UV light will find it difficult to obtain food. Hence, birds that have developed the ability to detect UV light will live long enough and reproduce, passing on these favorable characteristics to their offspring. Hence, birds that can detect UV light appears from birds who do not originally detect UV light.

Answer:

B

Explanation:

Nearly all movement in the body is the result of muscle contraction.

Answer:

Stage #1 Prophase: Chromatin fibers become coiled into chromosomes, with each chromosome having two chromatids joined at a centromere.

The mitotic spindle, composed of microtubules and proteins, forms in the cytoplasm.

The two pairs of centrioles (formed from the replication of one pair in Interphase) move away from one another toward opposite ends of the cell due to the lengthening of the ​microtubules that form between them.

Polar fibers, which are microtubules that make up the spindle fibers, reach from each cell pole to the cell's equator.

Kinetochores, which are specialized regions in the centromeres of chromosomes, attach to a type of microtubule called kinetochore fibers.

The kinetochore fibers "interact" with the spindle polar fibers connecting the kinetochores to the polar fibers.

The chromosomes begin to migrate toward the cell center.

Stage #2 Metaphase: The nuclear membrane disappears completely.

Polar fibers (microtubules that make up the spindle fibers) continue to extend from the poles to the center of the cell.

Chromosomes move randomly until they attach (at their kinetochores) to polar fibers from both sides of their centromeres.

Chromosomes align at the metaphase plate at right angles to the spindle poles.

Chromosomes are held at the metaphase plate by the equal forces of the polar fibers pushing on the centromeres of the chromosomes.

Stage #3: Anaphase: The paired centromeres in each distinct chromosome begin to move apart.​

Once the paired sister chromatids separate from one another, each is considered a "full" chromosome. They are referred to as daughter chromosomes.​

Through the spindle apparatus, the daughter chromosomes move to the poles at opposite ends of the cell.​

The daughter chromosomes migrate centromere first and the kinetochore fibers become shorter as the chromosomes near a pole.​

In preparation for telophase, the two cell poles also move further apart during the course of anaphase. At the end of anaphase, each pole contains a complete compilation of chromosomes.

Stage #4 Telophase: The polar fibers continue to lengthen.

Nuclei begin to form at opposite poles.

The nuclear envelopes of these nuclei form from remnant pieces of the parent cell's nuclear envelope and from pieces of the endomembrane system.

Nucleoli also reappear.

Chromatin fibers of chromosomes uncoil.

After these changes, telophase/mitosis is largely complete. The genetic contents of one cell have been divided equally into two.

Stage #5 Cytokinesis: Cytokinesis is the division of the cell's cytoplasm. It begins prior to the end of mitosis in anaphase and completes shortly after telophase/mitosis. At the end of cytokinesis, two genetically identical daughter cells are produced. These are diploid cells, with each cell containing a full complement of chromosomes.

Cells produced through mitosis are different from those produced through meiosis. In meiosis, four daughter cells are produced. These cells are haploid cells, containing one-half the number of chromosomes as the original cell. Sex cells undergo meiosis. When sex cells unite during fertilization, these haploid cells become a diploid cell.​

Answer:

Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. ... A typical species becomes extinct within 10 million years of its first appearance, although some species, called living fossils, survive with little to no morphological change for hundreds of millions of years.

Explanation:

# CAUSES OF ANIMAL EXTINCTION

Demographic and genetic phenomena.

Destruction of wild habitats.

Introduction of invasive species.

Climate change.

Hunting and illegal trafficking.

# Basic causes of extinction are as follows

2. Excessive hunting and killing of wild animals.

3. Poaching for purpose of meat, skin, fur, ivory, and rhino horns etc.

4. Capture and export of new species in large number.

5. Introduction of exotic species.

6. Excessive use of pesticides, fungicides, and other toxic chemicals.

7. Conversion of fertile land in the desert by overgrazing of domestic animals.

8. Deforestation leading to loss of covers or shelter to wild animals.

9. Excessive use of plant wood for timber, charcoal or fire purpose.

Answer:

Evaporation

Explanation:

Evaporation is the process in which percipitation moves higher to lower elavations on the ground. Evaporation is when the sun heats up and dries out the water causing it to rise up to the clouds which then causes rain for another time. ( I am not completely sure)

The correct option is B.

Alpha gamma coactivation is critical for maintaining the appropriate tension on the spindle organ during contraction of extrafusal fiber.

Alpha‐gamma coactivation is a process that the muscle use to keep or maintains it's length. It works in a way that when the muscle contracts or relaxes , the sensory neuron send the information to the central nervous system about what happen to the muscle. This lead the intrafusal and extrafusal fibers to contract.

Alpha-gamma coactivation enhance the muscle spindles ensure its sensitivity to stretch the muscle lengths.

Therefore, Alpha gamma coactivation is critical for maintaining the appropriate tension on the spindle organ during contraction of extrafusal fiber.

Answer:

Biomes differ in the amount of precipitation they receive, their temperatures, and the life that inhabits each biome.

Explanation:

Biomes differ in the amount of precipitation they receive, their temperatures, and the life that inhabits each biome.

For example, the types of organisms found in the subtropical desert differ drastically from the organisms found in a tropical rainforest. Each organism is well-adapted to its environment, and a subtropical desert and tropical rainforest are two very different biomes.

If you look at the graph below, you can see that the tropical rainforest has high average temperatures and high precipitation, whereas subtropical deserts have much lower precipitation and great variation in average temperature.

Explanation:

The left side of the heart contains the left atrium which allows oxygen rich blood to flow through the mitral valve and into the left ventricle. Whereas the right side of the heart contains the right atrium which allows the blood with poor oxygen levels to enter the right ventricle through the tricuspid valve.

Also, the left ventricle is larger than the right ventricle because the left ventricle is responsible for pumping the fresh oxygen rich blood throughout the body.
