Answer:
In the nitrogen fixation process, nitrogen fixing bacteria converts the N2 in the atmosphere into NH3 (ammonia). This bacteria binds hydrogen molecules with the gaseous nitrogen to form ammonia in the soil. ... From the conversion of ammonia to nitrites, bacteria also aids in this process called nitrification

1. Using Mendel's Law of Segregation and Law of
Independent Assortment, explain how meiosis leads to genetic variation.
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.

who is credited with developing the theory on systems?
Answer:
Ludwig von Bertalanffy
Explanation:
The graph below shows the change in the frequency of one allele over 500
generations in a large population. Which of the following statements
describes the change depicted in the graph?
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.

Describe Hydrogen Bonding.
BEST ANSWER GETS BRAINLIEST
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.
why a genetic bottleneck can be an important evolutionary factor for a species
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.

Suppose two leaf-eating species of animals live in a habitat where there is a severe drought and many plants die as a result. Which term describes the kind of relationship the two species probably will have?.
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.

Which process does the grass used to make the food this horse needs?
A.) Photosynthesis
B.) Respiration
C.) Eating
D.) Digestion
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.
in phantom limb syndrome, which sensory pathway is responsible for conveying the sensory neuron activities?
The experience of the phantom limb syndrome involves the subjective sensation of the patient, the processes involved in this sensation are: both sensitive activity and the motor pathway.
The somatic nervous system is made up of mixed nerves (mixtures of sensory and motor axons) that emerge from the central nervous system, innervate the somatic effectors (skeletal muscles).Somatic motor pathways begin in the motor areas of the cerebral cortex, the projection neurons in that cortex emit axons that descend through the brain stem until they reach the spinal cord.Patients with this syndrome experience the sensation that the amputated limb is still attached to their body, since the brain continues to receive messages from the nerves that originally carried the impulses from the lost limb.Therefore, we can conclude that Phantom Limb Syndrome is the perception of sensations, which include pain of an amputated limb, where both sensory activity and the motor pathway have an action on said sensations.

What type of energy is used? Photosynthesis transforms ___________ energy into ___________ energy in ___________ molecules.
Answer:
Photosynthesis converts solar energy into chemical energy that plants use to make glucose so they can grow.
Explanation:
During photosynthesis, solar energy is converted into chemical energy in the form of ATP molecules.
----------------------------------------------------------------------------------------------
During photosynthesis solar energy is converted into chemical energy in the form of energy rich bond of ATP molecule.
ATP (Adenosine triphosphate) and ADP (Adenosine diphosphate) molecules are termed currency of energy. ADP molecule is converted into ATP molecules, whenever energy is available in certain exothermic reactions of metabolism.
ATP molecules are store- house of energy. ATP molecule is broken down into ADP molecule in presence of enzyme ATPase, releasing energy whenever energy is required.
The synthesis of ATP molecules, utilizing solar energy during photosynthesis, is termed photo-phosphorylation.
These ATP molecules produced during light reaction of photosynthesis are utilized in dark reaction of photosynthesis (Calvin cycle).
ATP molecules synthesized during photo-phosphorylation may also be used in other metabolic reactions.
Photo-phosphorylation is of 2 types, i.e. Cyclic and Non-cyclic photo-phosphorylation.
Chlorophyll molecules entrap solar energy . There are 2 types of photo systems in chlorophyll. These are photo-system -I and photo-system-II .
The electrons of chlorophyll molecule of photo-system I get excited which pass through series of electron carriers in electron transport system arranged in the order of decreasing energy level.
During the passage of electrons from carriers of higher energy level to the carriers of lower energy level, the energy is lost which is utilized for converting ADP molecule into ATP molecule.
Photo-system I is concerned with light reaction of photosynthesis only, constituting cyclic photo-phosphorylation.
The electron transport during Photo-system II results in the synthesis of NADPH2 in presence of enzyme NADP reductase. NADPH2 is used in reduction reaction of Calvin cycle.
Both Photo-systems participate in non-cyclic photo-phosphorylation that results in the synthesis of NADPH2 in addition to the synthesis of ATP molecules.
The breathing rate of an aquatic animal is more than that of of a terrestrial animal . Why ?
Answer:
Since the amount of oxygen dissolved in water is comparatively lower than that in air, the aquatic animals have to breath rapidly to take in sufficient oxygen. Thus, the rate of breathing in aquatic organisms is much faster than that seen in terrestrial organisms

What is an angiosperm? Provide 2 examples. PLEASEE
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.
