The element nitrogen has the atomic number 7 and an atomic mass of 14. How many neutrons does an atom of nitrogen contain? 14 7 0

Answers

Answer 1

Answer: A nitrogen atom contains 7 neutrons. You can work out the number of neutrons of an element by subtracting the atomic mass from the atomic number.

Which is a structure that contains the cell’s hereditary information and controls the cell’s growth and reproduction? nucleus Golgi apparatus ribosome mitochondrion

Answers

Ribosomes synthesize proteins, and mitochondrion convert chemical energy in foods, and those two aren't where hereditary information is stored. The Golgi apparatus changes and packages proteins for export, so that isn't correct. The Nucleus is the cell structure that stores hereditary information and manages cell growth/reproduction.

Plain and simple, the answer is Nucleus.

Which scientist proposed that cells come from other cells?a. Hooke
b. van Leeuwenhoek
c. Schwann
d. Virchow

Answers

Answer: c. Schwann

Explanation:

By the late 1830s zoologist Theodor Schwann along with botanists Matthias Schleiden proposed the cell theory. The cell theory states that all living cells comes from the pre-existing cells, the cell is the basis unit of life and all living beings are made up of cells. This theory describes the basis property of all the cells.

Virchow. Hooke named the cell. Leeuwenhoek saw the first cell. Schwann observed animal cells. Virchow observed cell division.

Answers

Answer: "Dyslexia has a biological/genetic basis."

Explanation:

Dyslexia is a learning disorder which occurs when there is a problem with the way in which the brain processes and interpretes written materials. This makes it difficult for the individual to recognize, spell or decode words. Dyslexia is characterized by difficulty in reading.

Answer:

Dyslexia has a biological/genetic basis.

Which would be an adaptation in a rainforest, but not in a tundra

Answers

Answer:

A beak that can dig into thick trees

A rainforest has many tall trees, often with large canopies and vines growing. As a result, oftentimes at ground level there are many shadows and darker shaded areas. An adaption to this environment might be dark fur to blend in with the background, so that prey can hide from predators or a predator can sneak up on prey. This wouldn't work as well on the tundra, where there is plenty of light, few trees, and the primary colors of the landscape are the green/yellow of the grasses.

Another example might be the ability to swing from tree to tree as you see with animals like spider monkeys. There are few trees on the tundra so this wouldn't be a useful adaption, but in a rainforest where there are plenty of trees clustered close together this is very useful.

What percentage of the light energy that is absorbed by photosynthetic algae from the sun is available as food for herbivores in the oceans? a. 60 percent
b. 2 percent
c. 25 percent
d. 15 percent

Answers

The percentage of the light energy absorbed by photosynthetic algae from the sun that is available as food for herbivores in the oceans is 2 percent (Option b).

Photosynthesis refers to the metabolic reactions by which algae and plants produce energy which isstored in the chemical bonds of simple carbohydrates (glucose) by using the energy from the sun and carbon dioxide.

The photosynthetic efficiency can be defined as the fraction of light energy from the sun that is successfully converted (and stored) into chemical energy.

Algae only convert 2-3% percent of incoming sunlight into organic compounds, the remaining 98% is lost as heat.

In conclusion, the percentage of the light energy absorbed by photosynthetic algae from the sun that is available as food for herbivores in the oceans is 2 percent (Option b).
