In scientific notation, the number 39,940,000,000 becomes

Answers

Answer 1
Answer:

Answer:

In scientific notation, the number 39,940,000,000 becomes 3.994 * 10^(10)

Explanation:

Scientific notation is a way to represent a long numerical value in a short form.

The standard way to represent a number in scientific notation form includes -

Some power of 10  multiplied by the initial number between 0 to 10

The given number is 39,940,000,000

This can be written as

= 3.994 * 10^(10)\n= 3.99 * 10^(10)

Answer 2
Answer: 3.994 x 10^10 since you move the decimal place 10 points

The purpose of the right ventricle is to: receive blood coming back from the lungs pump blood to the upper and lower body pump blood into the lungs to be oxygenated receive blood back from the upper and lower body

Answers

The right ventricle's function is to pump blood into the lungs so that it can be oxygenated. The correct option is C.

Thus, deoxygenated blood from the right atrium is taken up by the right ventricle and pumped into the pulmonary artery, which transports the blood to the lungs. Through the act of breathing, the blood obtains oxygen in the lungs and releases carbon dioxide.

The oxygenated blood is then returned to the left atrium of the heart where the left ventricle pumps it to the remainder of the body. As a result, the right ventricle's main job is to pump blood to the lungs where it may be oxygenated.

Thus, the ideal selection is option C.

in order to use the Hardy-Weinberg equation to calculate genetic variations in a population which of the following conditions must exist in the population

Answers

Answer: All organisms must reproduce.

Explanation: Trust me G

APEX. Just trying to help people out who also have this question.

Population of living creatures or living organisms.

Because what can reproduce is a living creature/organism.

Further explanation

The Hardy-Weinberg Principle states that alleles and genotype frequencies in a population will remain constant from generation to generation without any other evolutionary influence. These influences include perfect pairing, mutation, selection, genetic drift, gene flow, and Meiosis steering.

The seven assumptions underlying the Hardy-Weinberg equation are as follows:

  • Such organisms are diploid
  • only reproduce sexually
  • generation that does not overlap
  • random marriage
  • infinite population size
  • same frequency alleles in both sexes
  • no migration, mutation or selection

Enlarged roots and stems in plants are adaptations for _________________ and are often found in _______________ plants that must endure winter.

Answers

Enlarged roots and stems are found in plants that need to adapt for food storage in winter months. These types of plants lose their leaves during the winter months and cannot participate in photosynthesis, so the extra food storage helps them to survive.
The category of plants that lose their leaves are called deciduous plants. 

food storage; deciduous.

A complete digestive system is found in bears. How is the undigested food removed from a bear? A. Limbs are used to remove the waste. B. The one opening is dual purpose for intake and removal. C. The skin excretes waste. D. An opening specified for waste removal is present.

Answers


d. an opening specified for waste removal is present


Final answer:

Bears remove undigested food through an opening designated for waste removal, also known as the anus. This is characteristic of an alimentary canal system where food enters orally and waste leaves through a separate exit. This type of digestive system is referred to as monogastric.

Explanation:

In the case of bears, and other animals with a similar monogastric digestive system, the undigested food is excreted via an opening designated for waste removal as suggested in option D. The process begins in the mouth where food is broken into small particles. This food then travels to the stomach where digestion continues with the breakdown of large molecules. The digested nutrients are then absorbed into the body in the intestines. Any undigested food that is not absorbed is removed as feces through an opening known as the anus. This type of digestive system is also known as an alimentary canal, which is a complete system with an oral intake and a separate waste removal opening.

An egg is protected by its outer shell. However, the shell also allows moisture and air to pass through. Which cell structure performs a similar function?A:cell membrane
B:cytoplasm
C:nucleus
D:vacuole

Answers

Answer:

Cell membrane.

Explanation:

The cell is the basic unit of the living organisms. The cell consists of the various cell organelles like nucleus, mitochondria and Golgi. The cell membrane covers the cell boundary.

The outer shell protects the egg and allows the exchange of moisture. The plasma membrane performs the similar functions ad allows the transport of some selected particles only.

Thus, the correct answer is option (A).

A:cell membrane, is right
