Many people place bat boxes on their property to provide housing that attracts insect -eating bats. Explain how this activity has a positive effect on the environment.

Answers

Answer:

Bat boxes at homes provide housing to insect-eating bats which has two major positive effects on the environment:

Bat boxes provide bats a natural habitat and they act as natural pest control in the environment. They are very helpful for reducing or controlling the population of mosquito and balance the food chain in the environment.Bat is known as very good pollinators which helps in the pollination of flowers or spread their seeds. So bat boxes at home increase pollination in nearby areas and increase biodiversity in the environment.

Hence, bat boxes at houses have a positive effect on the environment.

Which of the following means a hormone that aids in growth of gonads?
Glycogenesis
Thyrotoxic
Pancreatitis
Gonadotropin

Answers

Answer:

thyrootoxic

Explanation:

The hormone which aids in the growth of gonads  is Gonadotropin. The correct option is gonadotropin.

Gonadotropins are  defined as the hormones which  play an important  role in the growth and development of gonads. The gonads refer to the male and female reproductive organs, such as the testes and ovaries. Gonadotropins stimulate the production of sex hormones and even  regulate the reproductive processes. These homones are essential for the normal functioning of the reproductive system.

Gonadotropins are  classified as glycoprotein hormones  which are secreted by gonadotropic cells of the anterior pituitary which is present in vertebrates.This family includes the mammalian hormones follicle-stimulating hormone (FSH) and luteinizing hormone (LH), the chorionic gonadotropins, human chorionic gonadotropin (hCG) and equine chorionic gonadotropin (eCG),as well as at least two forms of fish gonadotropins.

Thus, the correct option is gonadotropin.

Answers

Answer:

C. Understand the process

Explanation:

When scientists create models of earthquakes, they are trying to learn more about them to try and keep people safe in the event that one does happen. It is practically impossible to change the location of an earthquake or stop it from occuring, since earthquakes are caused by the movement of massive continental plates. Scientists also definitely do not want to increase the waves formed in the process, as this would contribute to the damage. Therefore, the correct answer is choice C, understand the process. Hope this helps!

Scientists use models of earthquakes, so as to: C. understand the process.

What is an earthquake?

An earthquake simply refers to a sudden, natural shaking of the ground, due to movements within the Earth's crust and upper mantle (lithosphere) which typically creates seismic waves.

In order to have a better understanding of the features of an earthquake and the processes that are associated with, scientists generally use models of earthquake.

In conclusion, earthquake models are simulations which can be used by scientists to better understand the process.

Length of the real cells = 7500 cm

Explanation:

A scale model is a physical representation of an object that has the same aspects as that of the object.

A scale model can be used in fields like engineering, film making,  salesmanship, etc

Length of the student's cell model = 15 cm

The scale is [tex]1:500[/tex]

So,

Length of the student's cell model / Length of the real cells  = [tex]1:500[/tex]

Why anaerobic respiration is rapid than aerobic respiration​

Answers

Answer:

The amount of pressure that is released.

Explanations:

Aerobic respiration is known as a major advantage, base of the amount of energy it releases. Aerobic respiration releases more energy than anaerobic respiration, causing it to become more rapid.

Answer:

Anaerobic respiration is a shorter process than aerobic respiration so a complete cycle of anaerobic respiration is shorter than one of aerobic respiration.

Explanation:

Aerobic respiration involves three stages: glycolysis (the breakdown of glucose into pyruvate), the Krebs cycle (the breakdown of pyruvate into carbon dioxide and hydrogen), and the electron transport chain (hydrogen produced in the Krebs cycle bonding to oxygen to form water).

On the other hand, anaerobic respiration has fewer stages. Anaerobic means 'without oxygen', and so the process takes place without needing any oxygen. In anaerobic respiration, glucose is broken down into pyruvate, just like in aerobic respiration, however due to the lack of oxygen, that pyruvate is broken down into either lactic acid (e.g. in humans), or ethanol (e.g. in yeast). This process is called fermentation, and it doesn't take as long as the Krebs cycle and the electron transport chain, so that's why anaerobic respiration is more rapid than aerobic respiration.

define the general difference between an autotroph and a heterotroph

Answers

Answer:

Explanation:

If we break down the word autotroph, auto means “self” and troph means "feeding" or nourishment. However, when we break the word heterotroph, we get hetero- meaning other, and troph meaning feeders.

This is the critical difference between these two groups. Autotrophs synthesize or make their own food whereas, heterotrophs cannot make their own food thus have to rely on others by eating or absorbing others. For example, plants are autotrophs because they can make their own food using photosynthesis, whereas, humans are heterotrophs because we have to eat others to survive.

Answer:

autotrophs  are organisms that can produce their own food from the substances around them using light or chemical energy

heterotrophs cannot synthesize their own food and rely on other organisms plants and animals for nutrition

The image shows the path of a ball that’s thrown.
At positions (A,B,C, or D) and (D,E,F, or G), kinetic energy is maximum. At position (B,C,D,or E), potential energy is maximum.

Answers

At position (A) and (G), kinetic energy is maximum. At Position (D), potential energy is maximum.

At point A and G kinetic energy will be maximum while Potential energy is maximum at point D.

Kinetic energy (KE) is initially provided to the ball while it is still in contact with the throwing hand. Once the ball leaves the hand there is no input of energy. As the ball rises the KE is transformed to gravitational potential energy (GPE). This GPE is effectively stored in the height of the ball.Now, when the ball falls back to the ground its potential energy is transformed into kinetic energy, which will continue increasing as it gains momentum, until it finally collides with a surface.
