Genes

Answer:

Explanation:

Hypophosphatemic rickets is a disorder characterized by hypophosphatemia (low level of phosphate in the blood), defective intestinal absorption of calcium, and rickets (impaired mineralization of cartilaginous growth plates)  or osteomalacia (impaired mineralization of the osteoid) unresponsive to vitamin D. It can be inherited or acquired.

When it comes to inheritable hypophosphatemic rickets, the disorder is most often inherited in an X-linked dominant manner. This means that the gene is inherited through the X chromosome and that one dominant allele is enough to cause it.

As the mother is heterozygous for the trait, she has one dominant and one recessive allele (XHXh). The father has one X chromosome, which he inherited from his mother, and as he has the condition, the dominant allele will be present on it (XHY).

This means that, if the child is a girl, she will definitely have the disorder. Girls inherit one X chromosome from each of their parents. Even if she inherited the one with the recessive allele from her mother, she would get the one with the dominant allele from her father.

If the child is a boy, he has a 50% chance to inherit the condition. Boys inherit the Y chromosome from their father and the X chromosome from their mother. As the mother is heterozygous, he can either get the chromosome without the dominant allele or the one with it. This means that there is a 50% chance of inheriting the disorder.

If we say that there are equal chances of this couple having female and male children, when we combine these results, we get a 75% chance of them inheriting hypophosphatemic rickets.

Answer: photosynthesis

Explanation:

If all fours plants were watered daily but placed in a closet receiving no sunlight then photosynthesis would not occur.

Photosynthesis is defined as the process through which plants convert carbon dioxide, water, and sunshine into oxygen and sugar for energy.Photosynthesis is primarily used to convert solar energy into chemical energy, which is then stored for use at a later time. The biological systems on the planet largely receive energy from this method.

Without light, plants will lose their color and deteriorate. Due to inadequate photosynthesis, the shoots exposed to "limited/no" sunlight were yellow/white in hue. The sprouts struggled to make enough chlorophyll to give them a green color since photosynthesis was hindered by the lack of sunlight.

Thus, if all fours plants were watered daily but placed in a closet receiving no sunlight then photosynthesis would not occur.

3/16 Kinked tail, obese growth

3/16 normal tail, normal growth

1/16 normal tail, obese growth

Explanation:

Kinked tail (K) is dominant over normal tail (k) and normal growth (N) is dominant over obese growth (n). Two mice that are heterozygous for both traits (KkNn) are crossed:

        KkNn    x    KkNn

offspring:

9/16 K_N_ - Kinked tail, normal growth

3/16 K_nn - Kinked tail, obese growth

Answer:

they immediately begin to search for food

Explanation:

Answer:

1. primary cause of human-created carbon emissions = burning fossil fuels

2. destroys natural carbon sinks leading to more carbon dioxide in the air = deforestation

3. emits methane from decomposing matter = waste disposal in landfills

Explanation:

1. "Fossil fuels" are nonrenewable resources that are considered essential for the operation of many factories and industries. Burning them accounts for most of the carbon emissions on Earth, and this leads to "global warming."

2. "Forests" are considered "carbon sinks" because they have a role of absorbing the carbon dioxide in the atmosphere. Cutting down the trees (deforestation) makes forests barren. It then leads to more carbon dioxide in the air.

3. Waste disposals in landfills contribute to the amount of methane that is released into the atmosphere. Methane is considered a potent greenhouse gas that affects people's health.

Answer: Lack of energy

Explanation:

Oxygen is needed in a process known as Respiration where it is used to produce energy from glucose. This energy is what the cell uses to continue whatever functions that it carries out which are needed for the body to survive. If the cells don't get oxygen, they can't make energy and if they can't make energy, they die.

Some cells are more important than others and so will need a constant supply of oxygen. The brain for instance requires 20% of the oxygen used in the body. If the body suffers from a lack of oxygen for whatever reason, brain cells begin to die within about 4 minutes.

The brain is extremely important as it directs the body. If the cells there begin to die, the body deteriorates and the body stops engaging in certain processes due to a lack of direction from the brain. This coupled with the other cells dying around the body will lead to even more deterioration till the body dies.

Answer:

The fossils are in several areas because the animals were very widely distributed and this is how the evolution of the different species is shown in different parts of the world.

Fossils are skeletal remains of animals impregnated in stone, if these are not found, their chemical composition becomes petroleum and that is how the formation of oil arises.

Explanation:

Another reason was that many animals lived together on two continents, these two continents suffered many ruptures due to the appearance of volcanoes and movements of the tectonic plates and that is how the lands separated and new seas appeared, and the species dispersed throughout the world evolving each one differently according to the environment where it was stimulated.

Answer:

The correct answer is - The myosin is arranged in dimers so that when one releases, the other is bound.

Explanation:

Myosin moves along the actin in the cycle of binding and releasing which is known as the duty cycle of myosin movement. Myosin is found in the arrangement of the dimer.

It remains in its position with the help of this dimer arrangement as one released in the duty cycle while the other bound and then the other bound and it releases.

Answer:

The reciprocal of the molar mass of sulfur

Explanation:

The number of grams = n

Mass of Sulphur, m = 30 kg

Molar mass of Sulphur, M = 32.1 g

The formula used :

n = m / M

Converting m in kg to gram

1000g = 1kg

(1000/kg) ÷ 32

To change the ÷ sign to *, we multiply by the reciprocal of the divisor

The divisor is the molar. Mass of Sulphur

Hence, we have ;

30*(1000g/kg) * (1/32.1)

Because of cell differentiation

Explanation:

Multicellular organisms are organisms that have many cells in their body system, unlike unicellular organisms that have just one. However, these many cells contained in a multicellular organism are of different types performing different functions.

Although they all have the same set of genes encoding the same proteins in them, they are able to become different and perform different functions via a process called CELL DIFFERENTIATION. Cell differentiation is the process whereby cells of a living organism becomes specific in their functions as they divide. This is a result of the REGULATED EXPRESSION OF GENES. The genes in each cell are not expressed at the same time, hence, they have different functions.

Answer:

Respiratory system - breathing is faster, lungs open up to take in more air

Nervous system - heart rate speeds up, senses become sharper

Muscular system - body moves to a safer space

Circulatory system - stress hormones are transported around the body

Explanation:

Organ systems are groups of organs that work together to perform a certain function in the body. The human body consists of eleven organ systems. Four of them are included in the question you were given.

The respiratory system is the system of organs that allow us to breathe. It includes the airways, lungs, and blood vessels.

The nervous system is the organ system that coordinates our behavior and transmits signals between different parts of our body. It consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body.

The muscular system is the organ system that permits movement of the body, maintains posture, and circulates blood throughout the body. It consists of skeletal, smooth, and cardiac muscles.

The circulatory system is the organ system that carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide. It consists of the blood, blood vessels, and heart.

Based on this information, we can conclude what function belongs to which organ system.
