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

Which climatic zone is always hot and humid? arid, tropical wet, temperate continental, Mediterranean

Answers

Answer:tropical wet, is the anwers

Explanation:

The tropical wet climate zone is the climate zone that is consistently hot and humid. This climate zone is characterized by year-round high temperatures and high humidity, with average temperatures of 80°F (27°C) or more, and annual precipitation of 59 inches (1,500 mm) or more.

What is tropical wet climate zone?

The tropical wet climate zone is a type of climate that can be found in areas close to the equator. It is distinguished by high temperature, year-round high humidity and abundant rainfall. Equatorial climate or tropical rainforest climate are other names for this climate zone.

One of the most ecologically diverse regions on Earth is the tropical wet climate zone, which is also an important supplier of natural resources such as timber, fruits and medicinal plants. Deforestation, climate change, and other human activities also pose threats to the region, and they have the potential to have major impacts on the natural and economic systems that depend on this climate zone.

Therefore, the tropical wet climate zone is the climate zone that is consistently hot and humid.

WILL GIVE BRAINIEST!!Scientists use models of earthquakes to (5 points)
change their location
stop them from occurring
understand the process
increase the waves formed in the process

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.

Answers

Answer:

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]

15 / Length of the real cells  = [tex]1:500[/tex]

Length of the real cells  = 15 × 500 = 7500 cm

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.

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.

O C. Interneurons are too slow at sending signals through the spinal

Explanation:

The reflex reaction is important in certain situations because interneurons are very slow to send signals through the spinal cord.

What is the reflex?

The reflex is an automatic (read immediate and constant) bodily reaction to stimulation. According to Pieron, the reflex corresponds to any activity or variation of activity of an effector (muscle, gland, etc.)

With this information, we can conclude that the reflex reaction is important in certain situations because interneurons are very slow to send signals through the spinal cord.
