Which organelle is like the brain of the cell

Answers

Answer 1
Answer:

Answer: Nucleus

Explanation:

The nucleus is referred as the brain of the cell because it contains the genetic information necessary to carry out cellular functions.

Inside the nucleus, there is the genetic material called chromosomes, made of DNA that carry the necessary instructions to direct cell activities. Because, DNA carries information necessary for the synthesis of proteins that form tissues and perform various biological functions.  The functions of proteins are to maintain their integrity, defend themselves against external agents, repair damage, control and regulate functions, and others.

Practically, proteins are in charge of almost everything in the organism. And since they are made according to the information encoded in the genetic material inside the nucleus, this organelle is called the brain of the cell.

What is top soil? How do living things help form topsoil?

Answers

Topsoil is the upper, outermost layer of soil, usually the top 2 inches to 8 inches. It has the highest concentration of organic matter and microorganisms and is where most of the Earth's biological soil activity occurs. Four elements constitute the composition of soil.

Animals burrowing and plant roots growing down into the soil create the pores in the soil for the air and the water.


The organic matter in the soil comes from the decay of dead plants and animals. Earthworms, bacteria and fungi are just a few of the organisms that live in the soil, feed on the organic matter and decay or recycle plant nutrients. All of the organisms that live in the soil are such an important part of the continuous, natural process of decomposing organic materials and preparing the soil for future plant growth

Only some organs contain cells true or false

Answers

False; everything in your body is made up of cells.
FALSE ,The body's functions are conducted by organs. Each organ is a recognizable structure (for example, the heart, lungs, liver, eyes, and stomach) that performs specific functions. An organ is made of several types of tissue and therefore several types of cells (see Cells). For example, the heart (seeHeart) contains muscle tissue that contracts to pump blood, fibrous tissue that makes up the heart valves, and special cells that maintain the rate and rhythm of heartbeats.r body is made up of cells

WILL MARK BRAINLIEST Scientists have been studying threats to coral reefs. The percent of reefs affected by various threats are shown in the figure below. A future global temperature increase may affect all categories on the figure. Predict which category would change the most from global temperature increases and propose a testable question that scientists could study. a. The biggest effect will be on the far right column that includes thermal stress with a greater percentage of reefs falling into the low and medium threat categories. Scientists could test whether reefs that have greater fishing risk also have greater thermal risk. b. The biggest effect will be on the far right column that includes thermal stress, with a greater percentage of reefs falling into the high and very high threat categories. Scientists could test whether reefs that have greater temperature changes have greater increases in watershed-based pollution. c. The biggest effect will be on the far left column that includes fishing, with a greater percentage of reefs falling into the high and very high threat categories. Scientists could test whether increased fishing causes increased marine-based pollution. d. The biggest effect will be on the far left column that includes fishing, with a greater percentage of reefs falling into the low and medium threat categories. Scientists could test whether reefs that have greater temperature changes have greater increases in fishing threats.
