Answer:
See the answer below
Explanation:
Normal height - H
Short height - h
Heterozygous - Hh
A cross involving heterozygotes would be Hh x Hh
Hh x Hh
HH Hh Hh hh
Since H is dominant over h;
HH and Hh would produce normal height phenotypes.
hh will produce a short height phenotype.
Thus;
Probability of normal height phenotype resulting from the cross = 3/4 or 75%
Probability of short height phenotype resulting from the cross = 1/4 or 25%

A newly identified virus infects a eukaryotic host cell without producing virions right away, with a long period where the host is largely unaffected by the infection. What's the best description of this virus?
A: This virus rapidly causes lysis of the host cell
B: This virus has a long period of latency
C: This virus is a bacteriophage
D: This virus can't replicate
The best description of the virus is that the virus cannot replicate. The correct option is D.
What is a virus?A virus is an infectious agent which is non-living normally, but it becomes alive when come in contact with any living cell. It causes many diseases in humans, animals, and plants.
Here, the virus is not producing virions, which means it doesn't cause lysis. It doesn't affect the host, so do not have a long period of latency, and is not a bacteriophage, so the virus is not replicating.
Thus, option D: This virus can't replicate is correct.

What is body systems and their interaction?There are numerous parts to the human body. Every physical portion serves a distinct purpose. To better comprehend how the human body's components interact with one another and work together as a whole, scientists divide the body into systems. A group of bodily parts that cooperate to carry out a specific task is known as a body system.
For instance, the integumentary system, that shields the body from its surroundings, is made up of the skin, hair, and nails. Another instance of an organ that guards the body is the immune system.

How does the DNA change during meiosis?
Answer:
Scotland
Law is a surname, of English, Scottish, Cantonese, or Chinese origin. In Scotland, the surname means dweller at the low; as in a hill. Another origin of the surname is a contraction of Lawrence, or Lawson.
Explanation:
Answer:When recombination occurs during meiosis, the cell's homologous chromosomes line up extremely close to one another. Then, the DNA strand within each chromosome breaks in the exact same location, leaving two free ends. Each end then crosses over into the other chromosome and forms a connection called a chiasma.

In quiet breathing, muscular effort is used mainly in inspiration, and expiration is largely passive, due to elastic recoil of the lung. It results in a pattern change between expiratory and inspiratory flow. Explain changes you observed in the recordings you obtained. 1 pts Enter your answer here
Answer:
During quiet breathing, the main muscular effort is made in the inhalation process and the expiration process is mainly passive as it depends on the inhalation.
The expiration occurs due to the elastic recoil that causes a decrease in volume. In this process, the contraction of the diaphragm helps in the inhalation which is least affected by the intercostal muscle. During quiet breathing, the rate of inhalation and expiration time is relatively proportionate to one another.
During quiet breathing, the main muscular effort is made in the inhalation process and the expiration process is mainly passive basically depends on the inhalation because of elastic recoil that causes a decrease in volume.
During this, the contraction of the diaphragm helps in the inhalation which is least affected by the intercostal muscle whereas quiet breathing, the rate of inhalation and expiration time is relatively proportionate to one another.
What is Breathing?Breathing is the process of moving air into and from the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen.

You have a circular plasmid containing 9 kb of DNA, and you wish to map its EcoRI and BamHI sites. When you digest the plasmid with EcoRI and run the DNA on a gel, you observe a single band at 9 kb. You get the same result when you digest the DNA with BamHI. When you digest with a mixture of both enzymes, you observe two bands, one 6 kb and the other 3 kb in size. Explain these results. Draw a map of the restriction sites.
Answer:
A nick is created between G and A in GAATTC when using Eco R1 site while a nick is generated between G and G in GGATCC when Bam H1 is used. The difference in the nicks created is the main reason you observe two bands when you digest the circular plasmid with a mixture of both
Explanation:
Circular plasmid containing : 9 kb of DNA
Eco R1 and Bam H1 are known as restriction sites in DNA ( i.e. special sequences found in a DNA ) hence they can be specifically cleaved by the restriction enzymes enabling the insertion of a gene. that is why you will get a same result when you digest the Plasmid with either Eco R1 or Bam H1
but A nick is created between G and A in GAATTC when using Eco R1 site while a nick is generated between G and G in GGATCC when Bam H1 is used. The difference in the nicks created is the main reason you observe two bands when you digest the circular plasmid with a mixture of both
Explain why the cell membrane is the brain of the cell, as opposed to the nucleus.
Answer:
because it holds the information needed to conduct most of the cell's functions.
Cell membrane controls the transport of molecules across the cell and its external environment, Thus, it is called as the brain of the cell.
Why is cell membrane important?Cell membrane regulates most of the cellular activities through the property of selective permeability.
It is responsible for maintaining the cellular equilibrium through influx and efflux of ions and molecules.
There are various receptors present on the cell membrane which regulates the vital biochemical processes taking place in the body.
Cell membrane functions in the cell-cell recognition and cell signalling through various receptors.
Cell membrane is important in regulating body homeostasis. It offers the protective environment to the cell.
Control and regulation of activities is processed through brain.
Therefore, cell membrane is considered as the brain of the cell.

Food webs in ecosystems become very complicated very fast. Explain why.
Answer:
Food webs are more complex than food chains, yet equally as useful in understanding the processes of ecological communities. A food web shows the flow of nutrients between different types of organisms which can help us understand the energy transfer as described before.
Explanation:
Food webs in an ecosystem involves the combination of two or more food
chains. This involves all the relationship an organism has with the others.
This makes the food web complex.
Food webs have different types of organisms present which ranges from
plants which are regarded as the primary producers to animals such as Lion
which can be regarded as a Secondary/tertiary consumer in the ecosystem.
The occasional change in the geography and seasons in the ecosystem
also makes it very complex as some animals exhibit different traits when
subjected to certain conditions. This makes analysis of energy flow and relationship sketchy to determine.
