20. Edward Lambert, an Englishman, was born in 1717. Lambert had a skin disorder characterized by very thick skin that was shed periodically. The hairs on his skin were very coarse, like quills, giving him the name "porcupine man." Lambert had six sons, all of whom exhibited the same traits. The trait never appeared in his daughters. In fact, the trait has never been recorded in females. Provide an explanation for the inheritance of the "porcupine trait

Answers

Answer 1

Answer:

The trait is Y-linked

Explanation:

The only plausible explanation behind the inheritance pattern shown by the porcupine trait is that it is Y-linked.

Y-linked traits are limited to the Y chromosome only, a sex chromosome that is peculiar to only the male gender. Chromosomally, females are XX while males are XY. Hence, only the male gender has the genetic capacity to inherit the porcupine trait. This is why only the sons of Edward Lambert, and never the daughters, exhibited the trait.

What is chemical water pollution?

Chemical water pollution refers to the presence of harmful chemicals or substances in water bodies such as lakes, rivers, and oceans. These chemicals may come from various sources, including industrial processes, agriculture, and human activities. Common types of chemical pollutants in water include heavy metals, pesticides, oil spills, and toxic waste.

Chemical water pollution can have harmful effects on the environment and human health, including reduced water quality, contamination of aquatic life, and the spread of waterborne diseases. Preventative measures, such as proper waste disposal and treatment, are necessary to minimize chemical water pollution and protect water resources.

process is most likely to be used by agricultural industries?
O use of transgenic crops
O crop diversification
O spraying of organic herbicide
crop rotation

Answers

Answer:

use of transgenic crops

Explanation:

Since transgenic crops are genetically modified, the pros are that: there is more crop yield, increased nutrients, etc.

The use of transgenic crops is most likely to be used by agricultural industries. Hence, option  A is correct.

What are transgenic crops?

Crops that have undergone genetic engineering techniques to alter their DNA are referred to as genetically modified crops. Plant genomes can be modified physically or by transferring sequences contained in T-DNA binary vectors using Agrobacterium.

The goal of introducing a gene combination into a plant is to increase its productivity and usefulness. This technique offers benefits like extended shelf life, increased yield, improved quality, pest resistance, heat, cold, and drought tolerance, as well as resistance to a range of biotic and abiotic challenges.

The use of transgenic crops is most likely to be used by agricultural industries. Hence, option  A is correct.

Answer:

The correct answer is - the different temperatures of incubators.

Explanation:

An independent variable is a variable in a study or research which is manipulated or changed to check or find the effect on the dependent variable. The independent variable is the only factor that changes in research while other factors remain constant that can affect the result in the study.

In this case or study, there is the only factor that is manipulated is the temperature of incubators is manipulated to see the effect of temperature on the number of microbial colonies. Thus, the different temperatures of incubators is the independent variable here.

in what ways can overpopulation be beneficial to differential reproductive success?

Answers

Answer:

Differential reproduction is called the one that occurs as a result of the differences between the individuals that make up a society or sample, where it is those with comparative advantages who manage to reproduce, while those who do not have said advantages tend to die out. It is, in short, a practical application of Charles Darwin's theory of natural selection.

Thus, if there is an overpopulation of a certain species, a series of effects will occur (such as the scarcity of resources, the lack of living space, etc.) that will tend to gradually decrease the population to return to an ideal number of individuals. In this aspect, differential reproduction will be applied, being able to reproduce those that have comparative advantages over the rest, which will inevitably become extinct.

Which is a difference between active and passive transport?
A. Eukaryotes are capable of active transport, while prokaryotes are capable of passive transport.
B. Cells only carry out active transport when they need to move, while passive transport occurs constantly.

C. Active transport requires ATP, while passive transport does not.
D. Cells with mitochondria carry out active transport, while cells without mitochondria carry out passive transport.

Answers

if i am not mistaken , the answer is C .

Active transport really needs ATP to work , while passive transport doesn’t need ATP .

The difference between active and passive transports is that active transport requires ATP while passive transport does not. the correct option would be C.

Active transports are the movement of materials in and out of the cell that requires the expedition of energy. The energy is usually in the form of Adenosine Triphosphate (ATP).

Active transport is unlike passive transport because the latter requires no energy. In other words, passive transports are spontaneous.

Active transport usually involves the movement of materials against their concentration gradients while passive transport is the complete opposite.

Examples of active transport include the sodium-potassium pump, movement of amino acids in the intestinal tracts of man, etc while examples of passive transport include simple diffusion of oxygen to the alveolar walls in the lung.

Using the Gizmo, determine how coal and petroleum (oil) are formed. Describe the steps required to form each fuel from atmospheric CO2.

Answers

Answer and Explanation:

Petroleum and coal are fossil fuels.  The degradation of the earliest plants forms them. These dead plants started to pile up and form peat. Then the pressure and heat from various geological procedures convert peat into coal. Coal is a combustible rock which contains 50% carbon. Anthracite, Lignite and bituminous are the types of coal, and the formation of coal depends upon the quantity of hydrogen, oxygen and carbon. Petroleum exists naturally in liquid form and formed by decomposed organic matter. Fossil fuels can be refined into usable substances. Gasoline, tar, lubricants and many other products are obtained from petroleum. There are two steps, which required to form fuel from atmospheric carbon dioxide. In first step carbon dioxide is converted into carbon monoxide. In the second step, carbon monoxide combines with hydrogen to form hydrocarbon fuels. The formation of fuel is a natural process when animals respire carbon dioxide release in the atmosphere.

14. a science student claims that a substitution mutation is less likely to affect gene function than an insertion or deletion mutation. use logical reasoning and evaluate this claim.

Answers

DNA functions in codons which are pairs of three amino acids. In substitution since one is taken out and replaced, only the codon that that acid would have been in is affected. With insertion or deletion every codon on is shifted due to the presence of a new amino acid

Because insertions and deletions produce a frame-shift that modifies the interpretation of following codons, they are frequently more detrimental than substitutions that modify only one amino acid.

What is a mutation?

A alteration in the DNA sequence of an organism is referred to as a mutation. Errors in the replication of DNA during the process of cell division, exposure to mutagens, or viral infections are all potential causes of mutations.

Base substitutions, deletions, and insertions are the three different kinds of DNA mutations that can occur.

Because an insertion or deletion results in a frame-shift that changes the reading of subsequent codons and, as a result, alters the entire amino acid sequence that follows the mutation, insertions and deletions are typically more harmful than substitutions, in which only one amino acid is changed. This is because frame-shifts change the reading of subsequent codons.
