Answer:
50 %
Explanation:
It is given that a woman gives birth to a baby boy. Her second child is also a baby boy. Now she is about to give birth to her third child. We have to determine the probability of the child to be a girl.
Here, the probability of the child to be a girl would be 50 % or 1 out of 2.
There are two possibilities and the possibilities would result a boy child or a girl child. So there are two possible outcomes and is equally likely with each child birth.
Also each child birth is an independent event, so the probability that the one results will occur do not depend on the previous births.
In the mouse model of malaria, the researchers injected Plasmodium-infected human red blood cells into the mice because the Plasmodium species had surface ligand proteins that bound only to cell membrane proteins of human red blood cells. Assume that the researchers noticed that some of the parasites no longer infected human red blood cells but instead infected mouse red blood cells. Predict the most likely cause of this change in the host specificity of the parasites. Plasmodium reproduces both sexually in the host vertebrate and asexually in mosquitoes. The researchers claim that the Plasmodium organisms that infect the two different types of red blood cells are likely to evolve into two separate species of Plasmodium. Based on the biological species concept, provide reasoning that would support the researchers’ claim.

name one disorder of the digestive system
Answer:
Stomach Flu
Explanation:
Stomach flu—or gastroenteritis—is an infection of the stomach and upper part of the small intestine. Common symptoms are diarrhea, vomiting, stomach pain, and cramps. Rotavirus and norovirus, which affect millions of people every year, are often the cause. Gastroenteritis often clears up on its own, but you lose fluids through diarrhea and vomiting. Prevent dehydration by drinking water and electrolyte drinks.
state and explain components of blood
Answer:
It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including transporting oxygen and nutrients to the lungs and tissues
Explanation:
Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in. Red blood cells are responsible for carrying oxygen and carbon dioxide. Platelets are responsible for blood clotting. White blood cells are part of the immune system and function in immune response.

Photoperiodism is one example of how a plant responds to changing seasonal conditions. Why is it important for plants to be able to respond to seasonal changes?
Answer:
It is important because plants respond to light depend, logically enough, on the plant's ability to sense light. Phototropism is a directional response that allows plants to grow towards, or in some cases away from, a source of light. Photoperiodism is the regulation of physiology or development in response to day length.

Explanation:
Fish exchange gases by pulling oxygen water through their mouths and pumping it over their gills. So Basically, Its Similar to Our Lungs For us to breathe Like Fish.
Body system in humans which has a similar function to the gills in a fish is respiratory system.
What is a gill ?
A gill is a respiratory organ that many aquatic organisms use to extract dissolved oxygen from water and to excrete carbon dioxide.
What is a respiratory system ?The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants.
The primary purpose of gills and lungs in humans is to exchange gases, take oxygen in and release carbon dioxide out. Both lungs and gills have a bed of very small blood vessels with thin walls that the gases can easily travel across.To know more about respiratory system here

Which section of the article BEST explains why the development of CRISPR-Cas9 is significant for the scientific community?
Answer:
It allows the scientists to activate gene expression instead of cutting the DNA.
Explanation:
The development of CRISPR-Cas9 is significant for the scientific community because this development allows the scientists to activate gene expression instead of cutting the DNA. This technique allows the scientists and researchers to study the function of the gene. Before development, Cas9 enzymes produced by the CRISPR system binds to the DNA and cuts it by shutting the targeted gene off so this development of CRISPR-Cas9 enables the scientists to activate gene expression instead of cutting the DNA.

A man and a woman have a child together. The mother's blood type is type O and the child's blood type is type A What could the father's genotype be?
Answer:
iAiA or iAi = Type A
Explanation:
Blood group in humans is controlled by a gene with multiple alleles. The alleles iA and iB are co-dominant over one another but dominant over allele i. In the blood type:
iAiA or iAi - type A
iBiB or iBi - type B
iAiB - type AB
ii - type O
According to this question, a man and a woman have a child together. The mother's blood type is type O (ii) and the child's blood type is type A (iAi). This means that the father's blood type must be a type A with genotype "iAiA or iAi".

Which process begins the formation of sedimentary rock?
Water that reaches the ground and moves horizontally towards rivers, streams, and lakes is called runoff.
A. True
B. False
Answer:
A. True
Explanation:
flow off a hill slope directly to a stream in the form of runoff, or it may flows downward through the unsaturated zone to reach the water table. The area at the stream or lake to which the groundwater is flowing. Recall that water is flowing in pores where there is friction, which means it takes work to move the water.

How is information for a specific protein carried on the DNA molecule?
a. as a sequence of nucleotides
b. in the double helix shape of the condensed chromosome
c. in the ratio of adenines to thymines
d. as a pattern of phosphates and sugars
Answer:
b
Explanation:
Genetic information is carried in the linear sequence of nucleotides in DNA. Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs. ... In eucaryotes, DNA is contained in the cell nucleus.
The information for a specific protein is being carried on the DNA molecule as a sequence of nucleotides. Hence, option (a) is the correct answer.
Nucleic acids are of two types. They are namely deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA molecule carries the information for a specific protein. They are described as follows:
DNA is the genetic material of the cell DNA molecules undergo a process called transcription to code for codons on mRNA strand These codons tend to pair with tRNA molecule which holds the amino acids The amino acids will then form a chain in the sequence of DNA nucleotides to result in protein formationThus, we can conclude that the information for a specific protein is being carried on the DNA molecule as a sequence of nucleotides. Thus, option (a) is the correct answer.

Which conclusion is supported by the fact that the black-breed boar, with its quality meat, and the white-breed sow, with its quality fertility, are swine that are often matched for mating? Animals are often paired based on physical traits and personal compatibility. Strong reproductive capability is the most important trait in animal breeding. Selective breeding combines ideal traits of animals to replicate in offspring. Swine are the only agricultural animal species that are currently crossbred.
Answer:
Selective breeding combines ideal traits of animals to replicate in offspring
Explanation:
Selective breeding is the process which involves choosing parents with particular characteristics to breed together and produce offspring with more desirable characteristics. It is also known as artificial breeding and provides both plants and animals with greater variation and higher chances of survival. Selective breeding can be used to produce plants with bigger and tastier fruits and vegetables, crops with greater resistance to pests and diseases, and bigger animals that can be used for meat or milk production. The process of selective breeding is of great importance to the farmer today as it has brought about greater economic advantages.
In the instance of the black-breed boar and the white-breed sow being matched for mating, the reason is to combine these desirable traits in their offspring. The black-breed boar produces quality meat while the white-breed sow has quality fertility. Mating between these two breeds will produce offspring which has both traits of quality meat production as well as quality fertility.
