<h2>DNA Mutations</h2>

Explanation:

(A) A base-pair deletion

Insertion or deletion brings about a frame shift that changes the perusing of consequent codons and, hence, adjusts the whole amino acid arrangement that follows the transformation, additions and cancellations are normally more harmful than a substitution in which just a solitary amino corrosive is modified
DNA changes brought about by mutagens may hurt cells and cause certain illnesses, for example, malignancy
Instances of mutagens incorporate radioactive substances, x-beams, bright radiation, and certain synthetic compounds

When making yogurt, bacteria and milk are mixed together and set in a warm area. The container is sealed and no gasses are allow

Ivenika [448]

Answer:

When making yogurt the tart flavor get in the end is more likely because the bacteria have carried out a type of respiration named lactic acid fermentation (option C).

Explanation:

The process of obtaining yogurt from whole milk involves the association of the bacterial species Streptococcus and Lactobacillus. In order to carry out the lactic acid fermentation that produces yogurt, the bacteria act in a different way:

Streptococcus is in charge of removing the oxygen from the milk product.
Lactobacillus promotes the conversion of lactose sugar into lactic acid.

This fermentation process leads to the conversion of milk into a coagulated and tart flavor product.

Other options are not correct because:

A. Photosynthesis : is the process that occurs in plants to obtain chemical energy from sunlight.

B. Alcoholic fermentation: in this chemical process alcohol is obtained from the fermentation of a sugar.

D. Aerobic cellular respiration: does not involve fermentation, but the series of processes that convert glucose into energy.

All of the cacti is removed from a desert ecosystem, what would happen to the population of cactus dwelling birds and in turn th

pishuonlain [190]

The population of cactus dwelling birds will decrease and that of the animal they eat will increase.

Explanation:

When cacti is removed from the desert ecosystem, the birds that have their nest on the cacti will no longer have a home so they will migrate to other areas with favorable ecosystem.This will reduce the number of birds in this ecosystem.In turn, the animals that were feed by the birds will have the chance to multiply in numbers because a predator has been removed in the ecosystem.

Leonard designed a parallel circuit to light two lightbulbs. But his circuit doesn’t work. Which two items in the circuit must b

tamaranim1 [39]

In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component.

If two or more components are connected in parallel they have the same potential difference ( voltage) across their ends. The potential differences across the components are the same in magnitude, and they also have identical polarities. The same voltage is applicable to all circuit components connected in parallel.

If each bulb is wired to the battery in a separate loop, the bulbs are said to be in parallel.

Rosa eats a peanut butter sandwich for lunch. Peanut butter contains a lot of protein, and bread is mostly starch. Rosa plans to

vodka [1.7K]

Answer:

What does she need from the food she ate and the air she breathes so that she can go on her run?

A. Rosa needs carbohydrates rich food (bread) to carry out her jogging activity. Protein-rich food before exercise is not recommended unless she is on a weight loss program (diet plan).

B. Rosa needs oxygen to perform aerobic respiration, which is required for maximum release of energy (36 molecules per reaction run). Anaerobic reactions yield less energy (2 molecules of ATP per reaction run) and are not recommended.

How do Rosa's body systems work together to get the molecules she needs into her cells?

Rosa's body cells need carbohydrates (glucose) and oxygen to perform aerobic respiration for the release of maximum energy. The glucose and oxygen molecules are provided to the cells via diffusion into the bloodstream. During exercise/jogging, complex molecules of carbohydrates such as starch (present in bread) are broken down into simple molecules (glucose) which are diffused into the blood. Likewise, a high amount of oxygen is provided to the body's cells via diffusion in blood, which is carried out by the faster movement of lungs and heart. The combined action results in the supply of both types of molecules to enter the cell where mitochondria use these substrates to produce energy molecules (ATPs).

How do hair cells use these molecules to release energy for her body to run?

The substrates (glucose and oxygen) enters the bloodstream and then taken up to the cell. Then they are provided to the mitochondria for the release of energy in the form of ATP. This is why mitochondria are known as the powerhouse of the cells. Within the cell, energy is released in a three-step process, i.e. glycolysis, the Krebs cycle, and oxidative phosphorylation. Here glucose reacts with oxygen. In the end, aerobic respiration per reaction run produces 36 molecules of ATP which are sufficient to meet intensive energy needs. During excrcise, the supply of oxygen and glucose is also faster due to faster lungs and heart actions.

PS: Anaerobic respiration cannot meet energy demands faster because the reaction produces only 2 ATP molecules per reaction run.
