What is structure B pointing to?

Answer:

Mitosis, Meiosis, and both are written below

Explanation:

Mitosis: produces more somatic (body) cells, purpose is for healing and growing, the daughter cells are exact replicas

Meiosis: results in sex cells (gametes), results in eggs and sperm, purpose is for creating new individuals (eventually), each daughter cell is different, has 2 separate division stages

Both: Chromosomes need to replicate before the whole process begins, a form of reproduction

A renewable resource is different from a nonrenewable one by the fact that a renewable resource is replenished faster than it is used. Thus, the correct option for this question is D.

A renewable resource may be defined as a type of resource that significantly continues to exist in nature despite being consumed or can replenish itself over a period of time even as they are utilized by the organisms.

Examples of renewable resources may include wind power, solar energy, geothermal energy, biomass, etc. These resources are available in nature in unlimited amounts as compared to non-renewable resources.

Therefore, a renewable resource is different from a nonrenewable one by the fact that a renewable resource is replenished faster than it is used. Thus, the correct option for this question is D.

Answer:

See explanation

Explanation:

There is an equilibrium that exists between the carbon dioxide in the air and the carbon dioxide in the oceans. The temperature of the water affects its ability to hold carbon dioxide.

Hence, as the global temperature continues to rise and the water becomes warmer, its ability to hold carbon dioxide decreases. When this happens, the gas exchange across the air-ocean boundary is affected. There is now too much CO2 in the atmosphere owing to the disturbance of its air- ocean exchange equilibrium leading to more rise in temperature due to global warming.

Answer:

The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history. In land animals the respiratory surface is internalized as linings of the lungs. Gas exchange in the lungs occurs in millions of small air sacs; in mammals and reptiles these are called alveoli, and in birds they are known as atria. These microscopic air sacs have a very rich blood supply, thus bringing the air into close contact with the blood. These air sacs communicate with the external environment via a system of airways, or hollow tubes, of which the largest is the trachea, which branches in the middle of the chest into the two main bronchi. These enter the lungs where they branch into progressively narrower secondary and tertiary bronchi that branch into numerous smaller tubes, the bronchioles. In birds the bronchioles are termed parabronchi. It is the bronchioles, or parabronchi that generally open into the microscopic alveoli in mammals and atria in birds. Air has to be pumped from the environment into the alveoli or atria by the process of breathing which involves the muscles of respiration.

The cell wall is only found in plants, whereas the cell membrane is found in all living organisms, including plants. Only found in plants and a few fungi, bacteria, and algae. Introduce in all types of cells, including humans, animals, plants, and bacteria.

In biology, the base unit that can live by itself and is made up of all living organisms and body tissues.

Photosynthesis occurs in chloroplasts; cell walls allow plants to be strong and upright; and vacuoles help regulate how cells handle water and other molecules.

Mitochondria provide metabolites for epigenetic modifications and other nuclear-associated activities, and mitochondrial proteins have been discovered in the nucleus.

The material or protoplasm within a living cell, excluding the nucleus, is referred to as cytoplasm.

Whereas the nucleus is a dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane, containing the genetic material.

Thus, these are the basic differences between plant cell organelles cell membrane, cell wall, nucleus, cytoplasm, mitochondria, chloroplasts, and vacuole.

Answer:Oxidation and Hydrolysis

Answer:

The most vivid examples of chemical erosion are caves and sinkholes created in areas with a lot of underground limestone that ends up dissolving from acidic groundwater.

Explanation:

Hydrolysis - the breakdown of rock by acidic water to produce clay and soluble salts. Oxidation - the breakdown of rock by oxygen and water, often giving iron-rich rocks a rusty-coloured weathered surface.

Answer: C) They can contain contaminants that can enter the air during storms or high winds.

Explanation: A is wrong because I got it wrong (Sorry, can't give much explanation there).

B is wrong because water contamination does not directly relate to respiratory health.

D is wrong because fertilizers can impact respiratory health (Explanation seems lack-luster, but I feel like this is common sense).

Hope this helps :)

They can contain contaminants that can enter the air during storms or high winds.

The process of determining a few creatures possessing desirable characteristics to participate as the founders of the coming generation is Artificial selection.

The discovery of advantageous characteristics among living things by humankind, as well as the efforts performed to improve and maintain such traits throughout upcoming populations or years.

It follows the same procedure as evolutionary processes, with the exception that with biological evolution, nature determines the decisions rather than humans.

Thus the above response is correct.

Answer:

el ATP es la moneda energética que la célula utiliza para llevar a cabo diversas funciones metabólicas (incluida la reproducción)  

Explanation:

La adenosín trifosfato (ATP) es la principal fuente de energía para la mayor parte de los procesos celulares. La hidrólisis del ATP libera energía química almacenada en los enlaces de fosfato de la molécula, la cual es utilizada por la célula para llevar a cabo diversas funciones, incluida la reproducción. La hidrólisis de ATP genera en primera instancia adenosín difosfato (ADP) y un grupo fosfato libre (ortofosfato), esta es una reacción exergónica que libera una enorme cantidad de energía la cual es utilizada por la célula para llevar a cabo diversas funciones metabólicas incluyendo la síntesis de macromoléculas tales como, por ejemplo, proteínas del huso mitótico requeridas durante el proceso de división celular. El ADP también puede hidrolizarse para liberar energía, con la consecuente producción de adenosín monofosfato (AMP) y un segundo fosfato libre.

The law of independent assortment describes that it is not necessary for the plant to have only the predictable observations. New combinations of characters can also develop in plants. Thus, the correct option is D.

Mendel in his laws of genetics described that there are two different alleles present for all the characters in an organism where, one allele is dominant and the other is recessive.

The principle of Mendel's law of independent assortment describes how the different genes separate from each other independently when the reproductive cells develop in an organism. Independent assortment of genes and their corresponding traits were observed for the first time by Gregor Mendel in 1865 during his studies of genetics in the garden pea plants (pisum sativum).

Therefore, the correct option is D.

Answer:Tertiary consumers eat the secondary consumers and are usually carnivores (meat eaters).Secondary consumers are organisms that eat primary consumers for energy. Primary consumers are always herbivores, or organisms that only eat autotrophic plants. However, secondary consumers can either be carnivores or omnivores. Carnivores only eat other animals, and omnivores eat both plant and animal matter.
