What are phanerograms
Answer:
Phanerogams are terrestrial plants and more advanced than the cryptogams. These are also called as flowering plants. Following are the characteristic features of phanerogams: They have well-differentiated plants i.e. the plant body is divided into distinct root, shoot, and leaves.
The spermatophytes, also known as phanerogams or phaenogams, comprise those plants that produce seeds, hence the alternative name seed plants. They are a subset of the embryophytes or land plants.

Explain the experimental results that are seen in the absence of microsomes.
Answer:
The absence of microsomes allows the synthesis of only one protein.
Explanation:
The absence of microsomes influences the production of a single protein. This protein is vulnerable to protein and it can digest it quickly. This shows that the protein does not have a double layer of membrane and therefore must be treated with substances that help it overcome this vulnerability. This protein also does not have sugars linked to nitrogen and therefore should be treated with substances that are relevant, such as endoglycosidase H.
What are two ways that you could change the path of light? what materials would you need to do it?
Answer:
Light travels in a straight line until something alters its path. Here are three ways light's path can be altered: it can be refracted, reflected, or absorbed.
Materials such as a mirror or aluminum can reflect light.
Materials such as water or glass can refract light.
Materials such as coal or clack paint can absorb light.
The two different ways that a person could change the path of light are refraction and reflection of light.
What is Refraction and reflection?Reflection is the phenomena of bouncing back of the light rays when it strikes the medium such as air, water, etc on a plane. Refraction can be defined as the process of the deflection of light when it passes through a medium that lead to the bending of light rays.
The two main ways in which the light's path can be altered include refraction and reflection of light.
For example, materials such as a mirror or aluminum can reflect light, materials such as water or glass can refract light.

Two nitrogen-containing groups are used to make urea in liver cells. What two molecules of the urea cycle contribute these two nitrogen
Answer:
NH4+ and aspartate are the two molecules of the urea cycle contribute these two nitrogen.
Explanation:
Two nitrogen-containing groups are used to make urea in liver cells. The nitrogen atoms enter the urea cycle as NH4+ and aspartate. The first step of the urea cycle take place in liver mitochondria. In liver mitochondria, NH4+ combines with HCO3- to form carbamoyl phosphate.
So,
NH4+ and aspartate are the two molecules of the urea cycle contribute these two nitrogen.
Ammonia and aspartate are the two molecules of the urea cycle contribute
these two nitrogen used in the formation of urea.
These compounds are produced in the liver through the breakdown of
amino acids in the liver. The amino acids undergo transamination and
deamination reactions which results in the formation of these compounds.
The ammonia which is highly toxic is converted into urea which is then
excreted from the body.

• What is a virus? What are its components/structure and how does it affect the human immune system?
• What is the difference between a virus and a bacterium?
• Identify three ways that viruses and infectious diseases can be transmitted to humans and from human to human contact.
Simple short and easy search it up but try to use your own words instead of copying straight from the internet please
Answer:
Question 1 : A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea.
Question 2 (how does it affect the human immune system?) : Via cytotoxic cells. When a virus infects a person (host), it invades the cells of its host in order to survive and replicate. Once inside, the cells of the immune system cannot 'see' the virus and therefore do not know that the host cell is infected.
Question 3 (what are its components?) : The simplest virions consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virion to specific receptors exposed on the prospective host cell.
Question 4 (what is a viruses structure?) : All viruses contain nucleic acid, either DNA or RNA (but not both), and a protein coat, which encases the nucleic acid. ... Some viruses are also enclosed by an envelope of fat and protein molecules. In its infective form, outside the cell, a virus particle is called a virion.
Question 5 : As you might think, bacterial infections are caused by bacteria, and viral infections are caused by viruses. Perhaps the most important distinction between bacteria and viruses is that antibiotic drugs usually kill bacteria, but they aren't effective against viruses.
Question 6 : through the air, soiled objects, skin or mucous membrane, saliva, urine, blood and body secretions, through sexual contact, and through contaminated food and water.

The diagram shows two cells. Identify structures C, D, and E and explain how they work together to perform a specific process within the cell. Enter your answer in the space provided.
Answer:
C is the ribosome, D is the rough ER, E is the Golgi body. Ribosomes help make proteins, the rough ER makes proteins, and the Golgi body processes and delivers proteins.
Explanation:
Rough endoplasmic reticulum, or rough ER, is the term for the regions formed when these membrane-bound ribosomes coat the surface of the ER.
What is the role of endoplasmic reticulum?In both prokaryotes and eukaryotes, the translation of proteins is the main job of the ribosomes.
The big ribosomal subunit of the ribosome binds to the ER membrane and subsequently carries out protein translation there.
The Golgi complex before being delivered to their final locations, the endomembrane system is first introduced into the ER.
Different domains that are made up of sheets, tubules, and the nuclear envelope carry out the diverse ER tasks.
Therefore, C is the ribosome, D is the rough ER, E is the Golgi body.

A set of full-sibling juvenile wolf spiders was divided into two groups. One set was reared in low-temperature conditions, while the other set was reared in high-temperature conditions until they were adults. As adults, each individual was exposed to a predator at a moderate temperature and the groups exhibited very different escape behavior—those reared in low-temperature conditions fled sooner than those reared in high-temperature conditions. Which of the following can be concluded from these data?
a. Antipredator behavior exhibits a gene-environment interaction
b. Antipredator behavior is heritable
c. Antipredator behavior changes over time
d. There is an environmental influence on antipredator behavior
e. Genes and the environment affect antipredator behavior
Answer:
e. Genes and the environment affect antipredator behavior
Explanation:
Based on the data that was derived from the study we can conclude that Genes and the environment affect antipredator behavior. This is because regardless of the difference in the environment they were reared in both groups fled from the predator which is a genetic trait that has been passed down from generation. Yet, the group reared in low-temperature conditions fled sooner than those reared in high-temperature conditions meaning that the environment has affected the survival and antipredator behavior of the spiders.

Chymotrypsin, trypsin, and elastase are digestive enzymes called serine proteases. The serine proteases differ in substrate specificity. Chymotrypsin cleaves peptide bonds after aromatic or bulky hydrophobic side chains, trypsin requires basic amino acid residues, and elastase cleaves bonds following small uncharged side chains.
Which of the following amino acids have side chains that fit into the specificity pocket of chyrmotrypsin?
a. glycine
b. arginine
c. phenylalanine
d. alanine
e. aspartate
f. tyrosine
Answer:
The correct options are:
c. phenylalanine
f. tyrosine
Explanation:
The specificity of the pocket of chymotrypsin is for aromatic aminoacids o amino acids with bulky hydrophobic chains. From the list of amino acids, the aromatic amino acids are phenylalanine (with a phenyl group) and tyrosine (with a phenolic group).
From the rest, there are not amino acids with bulky hydrophobic side chains. Arginine has a 3-carbon side chain but it has a polar guanidino group, so it is not a bulky hydrophobic R-group. Alanine is hydrophobic but it is not bulky - it has only a methyl (-CH₃) group as R-group. Aspartate is not hydrophobic neither aromatic. Finally, glycine is very simple, it has only a -H as R-group.

The body system is responsible for creating new life.
Answer: yes, you are correct, but sometimes it is unable to create lives....then there is the option, of adoption.
Explanation: Men may not make enough sperm, or that sperm many not be strong ... can just happen (the same as some people might develop conditions ... to allow families who can't easily have babies to get pregnant and have families of their own. Most cases of female infertility are caused by problems with ovulation. Without ovulation, there are no eggs to be fertilized. Some signs that a woman is not ovulating normally include irregular or absent menstrual periods. Ovulation problems are often caused by polycystic ovarian syndrome (PCOS). another case is the body is just too old, and is shutting down. adoption is sometimes expensive, and has a lot of paperwork, but giving a child a family; is the best gift of all. some parents just aren't fit to take care of their child(children), so they go into foster care, and have the choice of either living on their own; or being adopted.....but in some cases, they don't have the choice, because they are too young to decide that.
A body system is a collection of parts able to work together to serve a common purpose growth, reproduction and survival.
The correct question is "The body system is responsible for creating new life" is called the reproductive system.The various part of a system depends on the other parts to perform the tasks. The various individual system works in lins with other systems to improve our chances of survival by maintaining a stable internal body environment.
Conclusively, the reproductive system is responsible for creating life. The the male and the female reproductive system differs.

All of the following options are examples of positive feedback EXCEPT:
a. increased strength and frequency of contractions as labor progresses
b.increased shivering and heat generation in response to cold temperatures
c. increased rate of fruit ripening in response to a gas released by nearby ripe fruit
d. increased platelet activation and recruitment to form a blood clot
Answer: The correct answer to the question is option B
INCREASED SHIVERING AND HEAT GENERATION IN RESPONSE TO COLD TEMPERATURES.
Explanation: Homeostasis is maintained by the control systems that detect and respond to changes in the internal environment, this is achieved effectively by the detector,control centre and the effector.
This dynamic process allows for the constant readjustment of many physiological variables.
Nearly all are being controlled by negative feedback mechanisms, positive feedback is much less common but important example is;
increased platelet activation and recruitment to form a blood clot and control of uterine contraction during childbirth.
The body temperature is one of the physiological variable that is controlled by negative feedback mechanism.
When the body falls below the preset level (close to 37°C), This is detected by specialised temperature sensitive nerve endings in the hypothalamus of the brain,where the body's control centre is located,the centre then activates mechanisms that raise the body temperature (the effectors). these includes;
- Stimulation of skeletal muscles causing shivering.
- Narrowing of the blood vessels in the skin reducing the blood flow to,and heat loss from the peripheries.
- Behavioural changed example; we put in more clothes to curl up.
When the body temperature rises within the normal range again,the temperature sensitive nerve endings are no longer stimulated,there signal to the hypothalamus will stop, therefore,the shivering stops too and the blood flow to the peripheries return back to normal.
This clearly explains option B which is the the correct answer of a negative feedback mechanism.
