4- Las plantas que viven en sitios húmedos y con poco sol tienen raíces poco profundas. Las que viven en sitios de mucho calor tienen raíces muy profundas. ¿Por qué?

Answers

Esto es debido a que en los lugares húmedos las plantas absorven el agua con las hojas y no necesitan hacer crecer la raíz para buscar agua. En cambio, las plantas que viven en lugares calurosos necesitan agua por lo que expanden las raíces hacia abajo para poder encontrar líquido e hidratarse.

What is the purpose of a gene

Answers

Answer:

Genes are a set of instructions that determine what the organism is like, its appearance, how it survives, and how it behaves in its environment. Genes are made of a substance called deoxyribonucleic acid, or DNA. They give instructions for a living being to make molecules called proteins.

Explanation:

Genes tell your body how to make all its proteins. Each new cell in the growing embryo receives a full set of genes. But not every cell needs to make every protein and cells make some proteins only at certain times. Some genes are instructions for proteins that regulate the activity of other genes.

Which of the following provides the best evidence that the circulatory system and the respiratory system work together to carry out their functions?
A : Nutrients are absorbed into the blood from the intestines.
B : Lungs expand and contract through movements of the diaphragm.
C : New red blood cells are generated in the marrow of bones.
D : Gases exchanged in the lungs are carried by the blood.

Answers

Answer:

D

Explanation:

Your first order of business should always be to see which answers involve both of the systems. A has the circulatory system (blood) but no respiratory system (intestines are the gastrointestinal system), B has the respiratory system (the lungs) but no circulatory system, C has the circulatory system (new red blood cells) but not the respiratory system (bones are the skeleton), and that just leaves D, so it has to be the answer. When you look at it to check, it includes both systems, as the lungs are part of the respiratory system and the blood is part of the circulatory system.

why are there no gram-positive archaea species but there are gram-positive bacteria species

Answers

Answer:

There are no gram-positive archaea because archaea lack peptidoglycan in their cell walls, meaning that the archaic cell walls are more similar to gram-negative bacterial walls, although they do show a greater variety of cell wall types. And bacteria do have this.

how is volume meausred

Answers

Answer:  Volume  is measured in cubic meters or cm

Explanation:  In the International System of Units (SI), the standard unit of volume is the cubic meter (m3). The metric system also includes the liter (L) as a unit of volume, where one liter is the volume of a 10-centimeter cube. Thus 1 liter = (10 cm)3 = 1000 cubic centimeters = 0.001 cubic meters, so.

Answer:

Volume can be measured in many ways. It can be found in a cube by length*width*height. It can be found in a cylinder by doing pi*radius^2*height. For a sphere it can be found by using (4 × π × r^3)/3. It can be found in a cone by doing (π × r^2 × h)/3. In a pyramid you can use (B × h)/3.

What is it about the structure of the alveolar-capillary unit that makes diffusion possible? Select all that apply.The capillaries are large. The cell wall of the alveoli is thin. Many capillaries surround one alveoli sac. There is always low pressure in the alveolar-capillary unit. The alveolar-capillary unit provides a large surface area.

Answers

Answer:

The most successful option would be: Many capillaries surround a sac.

Explanation:

Although in this question, I wanted to tell you that among all the options that is the most correct, but it is incomplete.

The capillaries that are in the alveolar unit are not only in great numbers to ensure gas diffusion but they are also SINUSOID capillaries where the cells of these capillaries do not have tight cell junctions, and there is a micrespace between cell and cell that forms the capillary wall.

And why is this? Because the greater the permeability of the capillary, the better the process of gas homeostasis or gas exchange at the alveolar level will be favored.

I hope I have completed your question, because it is very important that you know this, they are not simple capillaries that are only increased in number, but their sinusoidal permeable form makes them fulfill a VITAL function for the human being, this does not mean that all the capillaries of the body are like this, do not forget that we are speaking on time of the socket.

Answer:

B. The cell wall of the alveoli is thin

E. The alveolar-capillary unit provides a large surface area

Two separate species of squirrels have evolved after being separated by the Colorado River's erosion of the Grand Canyon. What type of speciation has occurred here?


A. Allopatric Speciation


B. Sympatic Speciation


C. Disruptive Selection


D. Group Behavior

Answers

Answer:

Option A

Explanation:

In this case the two species of squirrels have evolved when their combined population got divided into parts and was separated as a cause of natural calamity i.e Colorado River's erosion of the Grand Canyon, thereby forced to live in two different geographies and hence evolve differently from each other. The two geographies mentioned above remain disconnected by any natural barrier thereby restricting successful mating of the two population  groups of squirrels.

hence, option A is correct

Answer:

Allopatric Speciation is Correct for all future users.

The messages that scientists are sending into space are directed at intelligent alien life. Do
you think this is limiting? How could this affect scientists search for life beyond Earth?

Answers

Answer:

I think there is life beyond earth. Actually there most definently is. I think in  a way it could be limiting. It's the fcat that the ones out there may not even be able to receive the message as fast as we please. Who knows, it could be years, decades, maybe centuries before they make actual contact with us. Then again, maybe they already have. But, the way this could affect the study is the fact that (I doubt it) but maybe a message could be sent the wrong way, or they misinterpret it. That's the only think I can get off. Anyway, this can also depend on how much funding is going into space. This also brings up the question, "How much do we know about our own planet?

d) A student suggested that purple flowers are more likely to be visited by bees than white flowers.
Use your knowledge of natural selection to suggest how this might affect the number of purple and white flowers in the wild.

Answers

The purple flowers are more attractive than the whites ones because they are bright and eye catching so the bees would most likely visit the purple before the white flowers. Since this happens it would cause the white ones to become very rare since they aren’t getting pollinated

Answer: the purple flower is very attractive than the white flower

Explanation:

As more bees visits the purple flower there is less competition between the white.flowers. And as more purple flower is used by the bees the population of purple flower decreases and of the white flowers increases..
