what the answer fo this

Although the majority of the air we breathe is N2, most of the nitrogen in the atmosphere is unavailable for use by organisms. This is because the strong triple bond between the N atoms in N2 molecules makes it relatively unreactive. However organisms need reactive nitrogen to be able to incorporate it into cells.

Answer: Layer a is 500 million years old.

Explanation:

Trilobite is a member of the group of extinct arthropods found as fossils and they can be identified by the three-lobed as well as three segmented forms. These were the marine animals. These were appeared initially in the Cambrian Period. They used to live 542 million years ago so the fossils can be estimated to be aged of 500 above years old. These animals used to dominate in the sea area.

Answer:

Large prey less frequently

Explanation:

The less large prey they hunt, the more energy they'll have to be able to hunt other large prey after taking a break. Whereas if it were more small prey, it's a lot more running around chasing food that'll last them a couple seconds.

Answer:

The first option is correct;

A mutation to the p53 gene will result in excessive cell growth and division.

Answer:

A mutation to the p53 gene will result in excessive cell growth and division.

Explanation:

If there is a mutation to the p53 gene this mutation would result in an altered p53 protein and it won't be able to regulate cell proliferation effectively. This will make it unable to trigger apoptosis in cells that have damaged DNA. Over time as a result damage to the DNA will accumulate in these cells and such cells will continue to divide uncontrollably causing tumor growth.  

Answer: the process in which a cell changes from one cell type to another. Usually, the cell changes to a more specialized type. Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types.

Answer:

Good luck!!

Explanation:

Cell differentiation is an important process through which a single cell gradually evolves allowing for development that not only results in various organs and tissues being formed, but also a fully functional anima

Answer:

Explanation:

Answer:

Force = 78 N

Explanation:

Given data:

Mass = 39 Kg

Acceleration = 2 m/s²

Force generate = ?

Solution:

Formula:

F = ma

F = force

m = mass

a = acceleration

Now we will put the values.

F = 39 Kg × 2 m/s²

F = 78 Kg.m/s²

Kg.m/s² = N

F = 78 N

Explanation:

Explanation: During endocytosis (endo means inside) a cell will use its cell membrane to engulf an object which is outside of the cell. This process takes effort by the cell, so it needs to use energy (ATP!) The process which is the reverse of endocytosis is exocytosis (exo means outside - think exit).

Answer:

Endocytosis and exocytosis are active transport mechanisms in which large molecules enter and leave the cell inside vesicles. In endocytosis, a substance or particle from outside the cell is engulfed by the cell membrane. The membrane folds over the substance and it becomes completely enclosed by the membrane.

Answer:

b. Light energy is transformed into chemical energy and oxygen is released.

Explanation:

Photosynthesis is a process in which light energy from sun is transformed into chemical energy and oxygen is released. Therefore, option (B) is correct.

The chloroplast organelle of plant cells is where the process of photosynthesis takes place. The thylakoid membrane of the chloroplast is where the normal light response of photosynthesis takes place. Water and carbon dioxide, two of the main reactants, take part in the process. In the process of the reaction, the water is oxidized, producing oxygen as a byproduct. Carbon dioxide is reduced.

In essence, the chloroplast's chlorophyll pigment transports the electron and hydrogen from water to the acceptor known as NADP+ when it absorbs light.

Hence, light energy is transformed. Option (C) is correct.

something like oil spills and volcanic eruptions are some disturbances that would create a primary succession situation in an ecosystem, because they essentially occur in lifeless areas

Answer:

Your answer is C). If the plant is releasing water into the air, that must mean that there is an excess of water in the plant, and photosynthesis can only occur when sunlight is present.

Answer:

In biology, adaptation has three related meanings. Firstly, it is the dynamic evolutionary process that fits organisms to their environment, enhancing their evolutionary fitness. Secondly, it is a state reached by the population during that process. Thirdly, it is a phenotypic trait or adaptive trait, with a functional role in each individual organism, that is maintained and has evolved through natural selection. Historically, adaptation has been described from the time of the ancient Greek philosophers such as Empedocles and Aristotle. In 18th and 19th century natural theology, adaptation was taken as evidence for the existence of a deity. Charles Darwin proposed instead that it was explained by natural selection. Adaptation is related to biological fitness, which governs the rate of evolution as measured by change in gene frequencies. Often, two or more species co-adapt and co-evolve as they develop adaptations that interlock with those of the other species, such as with flowering plants and pollinating insects. In mimicry, species evolve to resemble other species; in Müllerian mimicry this is a mutually beneficial co-evolution as each of a group of strongly defended species (such as wasps able to sting) come to advertise their defenses in the same way. Features evolved for one purpose may be co-opted for a different one, as when the insulating feathers of dinosaurs were co-opted for bird flight. Adaptation is a major topic in the philosophy of biology, as it concerns function and purpose (teleology). Some biologists try to avoid terms which imply purpose in adaptation, not least because it suggests a deity's intentions, but others note that adaptation is necessarily purposeful.

The process of respiration produces energy for organisms by combining glucose with oxygen from the air. During cellular respiration, glucose and oxygen are changed into energy and carbon dioxide. Therefore, carbon dioxide is released into the atmosphere during the process of cellular respiration.

Linnaeus is credited with developing binomial nomenclature and classifying species into hierarchical groupings. So, the correct option is A.

Known as taxa, the Linnaean system of classification uses a hierarchy of categories (singular, taxon). Taxa include both species and kingdoms. The kingdom is indeed the biggest and most diverse organization. It is made up of creatures with just a few fundamental similarities. The kingdoms of plants and animals are two examples. Its smallest and most exclusive group is the species.

It consists of creatures that are enough similar to one another to mate and have children. A genus is a group of closely related species.
