Explanation:
just did it myself lol
Hormones are produced by endocrine cells. Hormones like FSH is released by pituitary gland and helps in menstrual cycle control, LH also comes from pituitary gland and helps in maintaining pregnancy.
What is endocrine cell?Endocrine cells are ductless cells which release their secretion i.e., hormones directly into blood.
The hormone FSH (follicle stimulating hormone) is secreted by pituitary gland. It helps in controlling menstrual cycle and stimulation of ovaries for egg production.
The hormone LH (Luteinizing hormone) is also secreted by pituitary gland, which helps in physical development and maintaining pregnancy.
Thus, both FSH and LH are produces by pituitary gland and their functions are to control menstrual cycle and maintaining pregnancy respectively.

What happens when two nitrogen atoms share electrons
Your answer would be A, they form a covalent bond.
We can rule out B and C, as they require completely different elements. An oxygen molecule is made up of what it sounds like, oxygen, and a water molecule, 2 hydrogens and 1 oxygen. Therefore, it is neither of these.
When you look at the two other choices, you can see they are both bond types. An ionic bond is the exchange of an electron and the subsequent attraction between the positive and negative charges, while a covalent bond is the sharing of electrons. When you look at the question, it specifically states "when they share electrons", meaning that the bond that forms is a covalent bond.

A forest fire destroys an area. A small population of trees and a large population of birds are both affected. Which type of limiting factor causes this?
density dependent
density independent
population dependent
population independen
The correct answer is B. Density independent
Explanation:
In biology, factors that limit a population are known as density limiting factors. These factors are classified into density-dependent if they affect populations with a high density such as predation or food availability or as independent if they affect different populations of animals despite their density which includes mainly disasters such as fires or floods.
This means the forest fire described is a density-independent factor because the population of birds and trees were reduced or limited but this did not occur because of the density of the population as all species in the forest are affected no matter if the population if high or low.

The first embryophytes in the plant kingdom???
a. Algae
b. Bryophytes
c. Pteridophytes
d. Gymnosperms
The first embryophytes were bryophytes, which include mosses and liverworts. They are considered the first land plants to have the capacity to form an embryo within protective structures. However, they lack the vasculature system seen in higher-order plants.
Explanation:The first embryophytes in the plant kingdom were bryophytes. Embryophytes are land plants that include all green plants, ranging from mosses to lush green trees. The term 'embryophyte' primarily refers to plants that are capable of forming an embryo within protective structures. The first plants to evolve this ability were bryophytes, which include mosses and liverworts.
These plants don't possess a vasculature system as seen in higher-order plants (pteridophytes, gymnosperms, angiosperms), and they don't produce seeds. Bryophytes are mostly distinguished by their life cycles, characterized by dominant gametophytes stage. They reproduce via alternation of generations where the dominant phase is the haploid gametophyte, which is contrasted with the vascular plants where the sporophytes are the dominant stage.

Chromosomes carry an organism's genetic code and are crucial for DNA replication and distribution. They ensure that each new cell receives the correct genetic information during cell division.
The structure made of DNA that gives the master instructions for the cell is the chromosome. Chromosomes are found in the nucleus of eukaryotic cells and they carry the genetic information necessary for the growth, development, and functioning of organisms.
To elaborate:
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. During cell division, chromosomes ensure that DNA is accurately copied and distributed in the vast majority of cell divisions.The DNA in chromosomes contains genes, which are specific sequences of nucleotides that code for proteins and other products necessary for cellular functions.The chromosome is crucial because it organizes the DNA into manageable units, allowing for accurate replication and distribution during cell division, ensuring that each new cell receives the correct genetic instructions.For example, in humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Each parent contributes one chromosome to each pair.

Explanation:
I don't know if I read that right, but dandelion tufts blow away and plant because of the wind, otherwise they cant move freely.
Answer:
1. 1a White tuft of dandelion seeds
3b cannot move about freely
Explanation:
The White tuft of dandelion seeds refers to the feathery filaments and seeds. It is carried along with moving air away from the parent plant. The wind carries the seeds of dandelion to other places. Once the seeds find suitable substratum and growth conditions, they germinate and form a new plant.
Since plants can not move from one place to another in search of better growth conditions and substratum, they depend on air, water, other animals, etc. for dispersal of their seeds.

The greatest way to illustrate mixtures in chemistry is to physically mix several compounds together. Diagram A is the most accurate representation of mixture.
Option A is therefore correct
How do we explain?Combinations that physically blend forms of substances that do not exhibit chemical bonding and may be separated using physical methods are referred to as mixtures. The materials are not all the same. Examples of mixtures are gases and sugar or salt that has been dissolved in water.
The heterogeneous mixture is referred to as varied, and the uniform composition is referred to as homogeneous. Unlike the previous pictures, which show compounds and molecules, the first diagram shows a mixture since it is composed of different subtypes.

conditions
B. So that no one else will know what is being studied
ООО
c. So that the experiment is cheaper and easier to conduct
D. So that a specific problem can be solved as quickly as possible
Answer: A. So that they respond to the test as they would under normal
conditions
Explanation:
It is a good idea to study experimental subjects in their natural environment because they respond to the test as they would under normal conditions (Option A).
A good experiment usually has into account all the variables that can affect the variable to be measured (i.e., the dependent variable).Thus, it is more suitable to test a hypothesis (either reject or confirm) only when having into account all variables that might affect the experimental group in normal conditions.A good experiment also uses a control group in order to make comparisons with the experimental group.A control group is defined as an experimental group consisting of subjects/individuals who do not receive the experimental treatment.In conclusion, it is a good idea to study experimental subjects in their natural environment because they respond to the test as they would under normal conditions (Option A).

Albinism is an autosomal recessive condition. Which circle graph above shows the genotype probability when an albino female
mates with a male that is heterozygous for the albinism trait?
Answer choice F
Answer choice G
Answer choice H
Answer choice J
Answer:
A; Half Aa and Half aa.
Explanation:
If you make a punnett square, the two genotypes will be Aa and aa, each half.
(sorry about the messy pic)
Answer:
Answer choice F
Explanation:
Since albinism is a recessive characteristic, let's assume that it has the "aa" alleles, so an individual who does not have albinism would have the "AA" alleles if he were homozygous and "Aa" if he were heterozygous.
If an albino (aa) female were to mate with a heterozygous, non-albino (Aa) male, we could fill in a punnet squad to determine what the offspring would be like. As we can see in the punnet square attached below, the result of this crossing would be 50% offspring "Aa" and 50% offspring "aa".
Which area is most likely to be the safest during a major earthquake?
Answer:
The area with loosely compacted soil is most likely to be the safest during a major earthquake.
Explanation:
Loosely compacted soil are those which are formed due to less stress that is been applied to the soil, as a result of desertification decreases in the soil density and the area whose soil is loosely compacted is the safest place during earthquakes as these areas have increased shear strength and less permeability that would protect you from earthquake as buildings constructed in these areas tends to be hard enough.
Hope it helps!
The safest place during a major earthquake is in a well-constructed earthquake-resistant building, as demonstrated in Niigata, Japan, and Japan’s strict building codes and earthquake drills.
The safest place during a major earthquake is in a well-constructed earthquake-resistant building. For example, some buildings in Niigata, Japan, constructed in the 1950s, remained structurally intact even when the city experienced a destructive earthquake in 1964. Strict building codes and earthquake drills in Japan ensure that structures can withstand seismic activity.
