Answers
Answer:
75%
Explanation:
If both parents are heterozygous (Ww), there is a 75% chance that any one of their offspring will have a widow's peak (see figure). A Punnett square can be used to determine all possible genotypic combinations in the parents. A pedigree that depicts a dominantly inherited trait has a few key distinctions.

Answer:
Heterotrophs
Hope this helps!
Why : A heterotroph is an organism that eats other plants or animals for energy and nutrients. The term stems from the Greek words hetero for “other” and trophe for “nourishment.” Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs.
Name two types of proteins that regulate the cell cycle. How do these proteins work?
Answers
Answer:
Internal and external regulators are two types of proteins that regulate the cell cycle. Internal regulators allow the cell cycle to proceed only after certain events occur. External regulators speed up or slow down the cell cycle.
Explanation:
I hope this helps :)
The two types of proteins that regulate the cell cycle are Cyclins and Cyclin-dependent Kinases (CDKs). These two groups of proteins are responsible for the progress of the cell through various checkpoints.
What are Proteins?
Proteins are made up of hundreds or thousands of smaller units called Amino acids. They are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body’s tissues and organs.
Cyclins regulate the cell cycle only when they are bound to Cdks and become fully active. The Cdk/cyclin complex must be phosphorylated, which further initiates other proteins to be phosphorylated that advances the cell cycle.
Retinoblastoma (Rb), is another group of tumor-suppressor proteins that regulates the cell cycle by monitoring the cell size.
Therefore, there are two types of proteins that regulate the process of the cell cycle are Cyclins and Cyclin-dependent Kinases (CDKs).

Bobcats are generally solitary and establish territories of a certain size where they hunt for food. What type of population dispersion would you expect bobcats to have?
Answers
Answer:
Uniform dispersion.
Explanation:
The bobcats' population distribution would be a uniform dispersion because they are distributed in an area in a balanced way. That is to say, that there is space between them and that each bobcat establishes its personal space when hunting and for their daily life. As they are solitary animals, they do not live in groups and only associate with other bobcats to reproduce themselves.

Why are seismic waves considered
mechanical waves?
A. They must travel through a medium, such as
the bedrock of the Earth.
B. They will only travel through empty space.
C. They travel in circles.
D. They do not require a medium.
Answers
Answer:
The correct answer is - option A.
Explanation:
The seismic waves are the waves that are the result of an explosion or the breaking of the rock within the earth. In other words, when these explosions or breaking cause an energy transfer within the earth are seismic waves. Seismic waves require a medium to travel and normally it is the earth.
The bedrock of earth is a great example of a medium for traveling these waves that make it a mechanical wave. Earthquake is the result of such waves.

What will be the effect of the damaged DNA? The role of p53 in regulating cell cycle prpgression in response to DNA damage
Answers
Answer:
Damaged DNA causes an increase in the number of mutations in the cell: this is extremely dangerous for the body and in fact this process is at the basis of the birth of cancer cells.
To avoid this, the cell is equipped with some molecular protective systems including the activation of the p53 protein. p53 induces recruitment of DNA damage repair systems and stops cell replication until the damage has been repaired. If the damage cannot be repaired p53 induces cell death through apoptosis

After a devastating forest fire, the surrounding area contained no life. After some time, small plants began to grow along the remaining soil.
Answers
Answer:
Yes.
Explanation:
Yes, small plants began to grow along the remaining soil because of the presence of seeds in the soil that sense suitable environmental condition and come out of the soil. The ashes of burn trees have huge amount of nutrients in the form of minerals that triggers the growth of small plants. After the destruction of forest, new plants grow on that land, this type of phenomenon is called ecological succession.
Answer: CORRECT (SELECTED)
Secondary succession
Explanation:
Secondary succession occurs when a previously occupied area is recolonized after a disturbance kills most, or all, of its community.

Civil engineers want to determine whether the porosity of surface soil affects aquifer recharge rates
Answers
Aquifer recharge is water that moves from the land surface or unsaturated zone into the saturated zone. Quantitative estimation of recharge rate contributes to the understanding of large-scale hydrologic processes. It is important for evaluating the sustainability of groundwater supplies, though it does not equate with a sustainable rate of extraction. Where contamination of an aquifer is a concern, estimating the recharge rate is a first step toward predicting solute transport to the aquifer. Recharge may cause a short- or long-term rise of the water table. Artificial drainage, e.g., with horizontal porous pipes buried at a chosen depth, is sometimes used to maintain a minimal thickness of vadose zone for agricultural or other purposes.
Recharge rates vary considerably in time and space. Recharge often occurs episodically in response to storms and other short-term, high-intensity inputs. For a given amount of infiltration, temporal concentration enhances recharge because it entails shorter residence times for water in the portions of the soil from which evapotranspiration takes place. Similarly, a larger fraction will become recharge if it is concentrated in narrow channels such as fingers or macropores, not only because this tends to hasten its passage through the unsaturated zone, but also because the water then occupies less of the volume of soil from which evapotranspiration takes place.
What scientist used radioactive bacteriophages to prove DNA is the
hereditary material passed from one generation to the next?
Answers
Answer:
Alfred Hershey and Martha Chase
Explanation:
In 1952 Alfred Hershey and Martha Chase were working with bacteriophages or phages, which are viruses that infect bacteria. They knew that a phage had an outer shell of protein and an inner core of DNA. In addition, from the electron microscope observations, they also knew that during infection the virus attacks the bacterium by its tails and introduces its genetic material into the bacterium to multiply using its metabolic machinery. They radioactively labeled two sets of phages: one with 32P (which marks only DNA) and another with 35S (which marks only proteins). In two parallel experiments, they infected bacteria with viruses marked on their DNA and with viruses marked on their proteins. The cultures were shaken with a mixer to separate the virus particles from the bacterial coatings. They then performed a centrifugation to separate the phages from the bacteria, so that the larger and heavier bacteria remain in the pellet, while the phages remain in the supernatant. They found that the radioactivity of 35S appeared in the supernatant while that of 32P appeared in the sediment, from which new radioactively labeled virus particles appeared, demonstrating that DNA was the genetic material.

The figure C represents Five kingdom classification.
What is Five kingdom classification?
The system of biological kingdoms is the way in which science classifies living things according to their ancestry over the course of evolution.
This means that all the species that make up these five large groups - some recent theories split them further into six or even seven - have common ancestors and therefore share some of their genes and belong to the same family tree.
As well as the kingdoms of living things there are other taxonomic categories within the same classification system such as, for instance, domain, phylum, class, order, family, genus and species.
Therefore, The figure C represents Five kingdom classification.
