Answer:

Acute illnesses generally develop suddenly and last a short time, often only a few days or weeks. Chronic conditions develop slowly and may worsen over an extended period of time—months to years.

Acute diseases refer to the medical condition that occurs suddenly and lasts for a shorter period of time. Chronic diseases develop slowly in our body and may last for a lifetime. Chronic diseases are sometimes fatal.

An allele simply refers to a variant form of a gene. Alleles are vital to the phenotype of an organism.

Your information is incomplete. Therefore, an overview of alleles will be given. An allele simply means the forms of a given gene variant. Alleles are genetic sequences. They code for the transmission of traits.

Alleles are the variant forms of genes which are located in the same position. The changes in allele frequencies can show that genetic drift is taking place or the introduction of new mutations.

Hydrogen bonding is a interaction between two hydrogen atoms that is very essential for life on Earth. It is notoriously seen between water molecules, and it occurs when there is a slight disbalance in electrical charge between two Hydrogen atoms, and Oxygen atom that comprise water.  This slight imbalance makes the Oxygen slightly more electronegative, and the two hydrogen atoms slightly more electropostive.  The reason why water when spilled forms globules for this exact reasoning. The slightly positive charged hydrogen feels an electrostatic attraction to the Oxygen atom thus forming a strong bond. An interesting fact that comes from this electrical disbalance is that when salt is added to water, water is able to conduct electricity because of this disbalance in charge it can seperate the sodium chloride lattices into ions.

Answer:

Ludwig von Bertalanffy

Explanation:

Answer:

Homologous chromosomes can independently assort along the metaphase plate during metaphase 1, meaning it doesn't not matter the order in which they line up, making it have more diverse possibilities. The law of segregation says that one allele from a gene can go to either gamete randomly, therefore there are 4 genetically different gametes from each parent that can be formed and come together to form a genetically diverse person.

Eustachian Tube

Explanation:

Eustachian tube is the structure that connects the throat to middle ear. It performs an important role in the balancing of air pressure across the both sides and prevent from fluids building up in the ear.

The thing which is common between these two pictures is:

From the given image, we can see that there is image of ear and mouth and we can see that the outer ear is visible, while the mouth is wide open and we can see the interiors.

With this in mind, we can see that the Eustachian Tube is the structure which links the throat and ear and this performs the important function of regulating the air pressure that gets into the organs.

Answer:

Genetic drift decreases genetic diversity within a population.

Explanation:

Genetic drift decreases genetic diversity within a population. It is a change in allele frequencies due entirely to random chance and is more likely to affect smaller populations than large ones. Population bottlenecks can lead to genetic drift.

Answer: Angiosperms represent approximately 80 percent of all known living green plants. Examples range from the common dandelion to ancient flowers such as magnolias. Angiosperms also make up the vast majority of all plant foods we eat. (Ex. grains, vegetables, and fruits.) The angiosperms are vascular seed plants in which the ovule (egg) is fertilized and develops into a seed in an enclosed hollow ovary The ovary itself is usually enclosed in a flower, that part of the angiospermous plant that contains the male or female reproductive organs or both. fruits are derived from the maturing floral organs of the angiospermous plant and are therefore characteristic of angiosperms.

Competition is the kind of relationship these two leaf eating species of

animals will have.

Competition involves organisms vying for resources such as food, sunlight,

space etc in the ecosystem. The two leaf eating animal species are in

competition with each other for plant leaves.

When drought occurs and the leaves reduces, competition for food

increases in which the fittest survive and the less fit ones die from starvation.

Answer:

Photosynthesis

Explanation:

Just like trees and other plants, grass converts energy from sunlight into sugar through the process of photosynthesis. This energy is used to convert water and carbon dioxide into glucose. Carbon dioxide is absorbed through the stomata in the leaf and water is mainly derived from uptake in the roots. Photosynthesis makes the grass green and healthy.

Cellular respiration in living tissues is reduced at low temperatures. The amount of kinetic energy needed for chemical reactions like cellular respiration to occur decreases as temperature rises.  Thus, option A is correct.

As oxygen tension dropped, so did breathing rate, which eventually reached nil at low oxygen tensions.

Cell density had no bearing on this outcome. We provide a model to explain the observed impact of oxygen tension on cellular oxygen uptake.

As a result, increased cellular respiration is often associated with warmer temperatures.

Carbon dioxide concentration: The rate of respiration is inversely correlated with carbon dioxide concentration.

Increased carbon dioxide levels and a lack of oxygen have a negative impact on aerobic respiration rate.

Therefore, cellular respiration  is the metabolic process that breaks down organic molecules to release energy to be used by cells.
