Answer:

The third line of defense is referred to as the immune response. This defense is specific to a particular pathogen, and it allows the immune system to “remember” the pathogen after the infection is over.

In the process some of the mass of the hydrogen is converted into energy

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

Explanation:

I only know this as a answer..sry if its wrong.

Answer:

It requires trolling your friends skills

Answer:

overpopulation can occur when there are not enough preadators or the food web is out of balance, in some ecosystems overpopulation can really harm it as some organisms increase and decrease which can cause an extintion if it gets too out of hand.

Explanation: period.

Answer:The reefs create a shelter for organisms and food

Explanation:Therefore it now created a more populated area for more animals or organisms to live.

Answer:

Plato

Explanation:

Many animals depend on corals for food and protection. By restoring the reefs using this method, they may be able to protect other populations of organisms from declining as well.

Answer:

In a hot spring in Kamchatka, Russia, the two groups of genetically indistinguishable microbes parted ways. They began evolving into different species—despite the fact that they still encountered one another in their acidic, boiling habitat and even exchanged some genes from time to time, researchers report.

Hope this helps

Answer:

Explanation:

Others thing they share is that, both animals lay reproduce by laying of eggs.

It should be understood that, both reptiles and aves reproduce by laying of eggs, and that's another trait that they have in common.

Another one is that, there are some of the birds that are carnivorous in nature, just like the crocodile.

Explanation:

An ecological pyramid (also trophic pyramid, Eltonian pyramid, energy pyramid, or sometimes food pyramid) is a graphical representation designed to show the biomass or bioproductivity at each trophic level in a given ecosystem.

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?

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.

Answer:

true

Explanation:

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.

Explanation:

Answer:

Without the Sun's heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.

Explanation:

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.

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.
