Why do human offspring resemble their parents but are not identical to them? Explain.
Answer:
When dealing with two parties theres is going to be a resemblance to both parents slightly favouring ones characteristics more obviously but identical to one or the other would be an impossibility with two diffrent genetic pools mixing.
Human offspring resemble their parents but are not identical to them due to fact that they get half of their DNA and inherited features from each parent and crossing over.
Humans reproduce by the process called sexual reproduction. Sexual reproduction involves the fusion of sperm and egg called fertilization that means they get their genetic material from mother and father equally.
Offsprings are genetically similar to offspring but not identical due to these factors:
Offspring is produced by a combination of two different parent's gametes and each provides their genetic material to zygote.it generates variation in the offspring due to crossing over and fertilizationThese variations give them adaptable offspring as a survival advantage.Thus, the correct answer is - they get half of their DNA and inherited features from each parent and crossing over.

The immune system has two modalities, specific and nonspecific responses. Which of the following is an example of a nonspecific response?
A. an antigen binding to an antibody
B. inflammation at the site of an infection
C. a cytotoxic T cell attacking a pathogenic agent
D. lymphocytes activating plasma cells in the blood
B. Inflammation at the site of an infection is an example of a nonspecific response of the immune system.
What is non-specific immune response?Non-specific immune responses, also known as innate immunity, are the first line of defense against invading pathogens and are activated immediately upon exposure to a foreign invader. These responses are not specific to a particular pathogen and do not require previous exposure or recognition. Instead, they provide a general response that helps to prevent the spread of the pathogen and contains it until the specific adaptive immune response can be activated.
Examples of non-specific immune responses include physical barriers such as skin and mucous membranes, as well as physiological responses such as inflammation, fever, and the activity of phagocytic cells like macrophages, which engulf and destroy pathogens. Non-specific immune responses also include natural killer cells, which are able to recognize and kill infected cells, and the complement system, a group of proteins that help to enhance the ability of other components of the immune system to destroy pathogens.

A plant can have green (G) or yellow (g) leaves. It can also have a long (K) or
short (k) stem. A scientist is preparing a Punnett square for a dihybrid cross
of a plant with a genotype GgKk. What possible gametes can the plant
produce?
O A. GK, GG, KK, kK
OB. GK, Gk
Oc. GK, Gk, gk, gk
OD. GK, gk
Answer:
The options are incomplete, however, the question can still be answered based on general understanding. The possible gametes are:
GK, Gk, gK and gk
Explanation:
This question involved two different genes coding for leaf color and stem length respectively. In the first gene, the allele for green color is 'G' while the allele for yellow color is 'g'. In the second gene, the allele for long stem is 'K' while the allele for short stem is 'k'.
According to this question, a scientist is preparing a Punnett square for a dihybrid cross of a plant with a genotype GgKk. Based on Mendel's law of SEGREGATION, this plant with genotype: GgKk will undergo meiosis where the alleles of each gene will separate into possible gametes as follows:
GK, Gk, gK and gk
Note that, only one allele of each gene is present in each gamete.

O D. Using the fewest animals necessary for an experiment
Answer:
C. Taking blood samples from patients for research purposes
without consent
Explanation:
Generally, providers may not render medical services without the patient’s consent, unless performance of emergency, lifesaving care is necessary. Taking samples from a patient is a type of medical service; thus, state consent laws apply. In addition, providers may not disclose PHI without patient authorization.

An athlete throws the javelin 212 m. The average speed of the javelin was 15 m/s. How long was the javelin in the air?
Answer:
The correct answer is - 14.133 seconds.
Explanation:
The time that the javelin took in the air before landing after the 212 m throw can be calculated by simple distance and velocity formulas which say that the speed of an object is equal to the distance traveled by the object in unit time.
Given:
Speed or s = 15 m/s
Distance or d = 212 m
Then, the time or t =?
Solution:
By the formula, s = d/t
or t = d/s
t = 212/15
t = 14.1333
thus, the correct answer is - javelin was in the air for 14.1333 seconds.

The product of photosynthesis are option (C) glucose and (D) oxygen gas.
What is photosynthesis?The energy from light is converted into the form of chemical energy through a process known as photosynthesis, which is utilized by living creatures like plants. Through a process known as cellular respiration, this chemical energy can eventually be converted into usable fuel that can be utilized to power the activities of the organism.
It is standard practice to write the equation that describes the process of photosynthesis as follows: 6CO2 + 6H2O gives C6H12O6 + 6O2.
This suggests that chlorophyll, which takes in light energy and converts it into chemical energy, is responsible for the transformation of the reactants, which are comprised of six molecules of carbon dioxide and six molecules of water, into the products, which are one molecule of sugar and six molecules of oxygen.

Two species of fish are introduced to the same lake. Over time, only one species survives. According to Darwin's theory of evolution, what should characterize the surviving species
Answer: Both species must have competed for the same niche. The surviving species is better adapted or adapted better and outcompeted the other.
Explanation:
According to Darwin's theory of evolution (survival of the fittest), the surviving species would be fitter than the extinct fish.
What is the theory of survival of the fittest?Charles Darwin proposed the idea of the "survival of the fittest," which states that organisms that are most adapted to their environment have a higher chance of surviving and reproducing. Charles Darwin proposed natural selection as a crucial aspect of evolution.
Natural selection refers to the process by which an organism becomes more likely to thrive and produce more offspring the better it is able to get food and avoid becoming prey. The process of evolution is driven by this "survival of the fittest," which results in species surviving as a whole.
Thus, according to Darwin's theory of evolution, the surviving species would be fitter than the extinct fish.
