A computational biologist develops a computationally intensive program for DNA sequence alignment. When they use distributed computing techniques to run the program on four computers in parallel, they find a speedup of 4. In this case, what does a speedup of 4 indicate

Answers

Answer 1

Answer: The program completed in a quarter of the time with four computers versus one computer

Explanation:

Distributed computing simply means using distributed systems in solving computational problems and this is done as the problem is divided into many tasks, whereby the tasks are accomplished by one or more computers.

Following the information given in the question, a speedup of 4 indicate that the program completed in a quarter of the time with four computers versus one computer.

It is impossible for sperm to be functional (able to fertilize the egg) until after ________. Group of answer choices

Answers

Answer:

The answer is "they undergo capacitation"

Explanation:

Sperm migrate through uterine contractions and the energies of its flagella to the uterine tube. In sperm motility, reverse peristalsis is engaged in the uterus and uterine tubes. For a sperm cell to fertilize an egg, it takes approximately 24 hours. The surface of the egg changes as the sperm penetrates the egg, therefore no sperm is allowed within. The kid is fully genetic, including whether it's a boy or a girl at the time of fertilization. Until they are trained it is difficult for sperm to be working.

What is evolution?

Transition in the heritable traits of biological communities over time is referred to as evolution.

These traits are gene expressions that are passed down from parent to progeny during reproduction.

They have resulted in significant gains in standard of living, public welfare, wellness, and protection.

They have altered our perceptions of the universe and of ourselves in relationship to the world around us. One of the most fundamental concepts in modern science is biological evolution.

They are well-known for evolving different beaks that are suited to different food types, such as large seeds as well as invertebrates, enabling them to occupy different niches.

Thus, the correct option is C.

A meiotic error occurred during gamete formation, resulting in an egg that has 24 chromosomes. If that egg is fertilized by a normal sperm, how many chromosomes will be in the zygote

Answers

Answer:

47 chromosomes

Explanation:

Meiosis is a kind of division that reduces the chromosome number of the daughter cells by half i.e. 2n - n. It occurs only in reproductive cells to produce sex cells or gametes. In humans, meiosis occurs to produce gametes (egg and sperm) that have 23 haploid chromosomes.

N.B: Somatic human cells have 46 chromosomes

According to this question, a meiotic error occurred during gamete formation, resulting in an egg that has 24 chromosomes. If that egg is fertilized by a normal sperm i.e. sperm with 23 chromosomes. A zygote that posseses (23 + 24) = 47 chromosomes will be produced.

An anaerobic metabolic pathway that results in the production of two net ATPs per glucose plus two pyruvic acid molecules is glycolysis True False

Answers

Answer: True.

Explanation:

Glycolysis is a process that occurs in the cell cytoplasm, in which a 6-carbon glucose molecule is cleaved into two 3-carbon pyruvate molecules. Two molecules of ATP (Adenosine triphosphate, a molecule that acts as a source of energy to perform biological processes.) and two molecules of NADH are also obtained. It is a metabolic pathway responsible for oxidizing glucose in order to obtain energy for the cell. It consists of a series of consecutive enzymatic reactions, and when pyruvate is obtained, it continues to be used in other metabolic pathways in order to continue delivering energy to the organism. Glycolysis takes place both in the absence and presence of oxygen, so it is defined as an anaerobic process. Therefore, the final destination of the products obtained in glycolysis will depend on the conditions of the environment in which it is found, which will determine the metabolic pathway to be followed (i.e., whether oxygen is available or not). In the absence of oxygen, glucose will not be completely oxidized to carbon dioxide and water, generating fermentative products (lactic acid in animals and ethanol in yeast) producing only two net ATP molecules. In the presence of oxygen, the pyruvate obtained during glycolysis enters the Krebs cycle (to produce energy in usable form as ATP or GTP) and then undergoes oxidative phosphorylation (the process by which ATP is formed as a result of electron transfer from NADH or FADH2 to oxygen via a series of electron transporters) producing a net gain of between 36-38 ATP.

how would hemoglobin content differ in a person living in philadelphia compared to someone living in denver

Answers

Answer:

The correct answer is - the difference in altitudes.

Explanation:

The hemoglobin in the person of Denver who lives at a higher altitude than the person who lives in Philadelphia will be much higher. This is due to the fact that at higher elevation or altitude atmospheric pressure decreases that causes hemoglobin to stick to the RBCs and that results in less oxygen level in the body.

To compensate for this low level of oxygen levels hemoglobin content need to be higher in people living at a higher elevation.

(Choice D)
D

Answers

Answer:

C) Smallest fragment of DNA that traveled the fastest

Explanation:

During this gel electrophoresis, DNA passes through a agarose obstacle course, where the poles opposite to wells are positively charged electrodes. Since DNA is negative in charge, when it is placed in wells and electric current is run, DNA will try to run towards the positive end.

Shorter DNA segments can easily  "wiggle" through the pores of the gel whereas, longer DNA segments need to do more "squeezing" to move down the gel.

Therefore, Band X in this figure is the shorter DNA segment as it move through the lane at a faster rate and reaches very far when compared to longer DNA segments.

Smallest fragment of DNA that traveled the fastest. So, the correct option is (C).

What is Gel electrophoresis?

Gel electrophoresis is defined as the technique that is used in laboratories to separate charged molecules such as DNA, RNA and proteins according to their size where the charged molecules move through a gel when an electric current is passed through it.

During gel electrophoresis, the DNA passes through an agarose barrier course, where opposite poles of the wells are positively charged electrodes, so the DNA is negatively charged when it is placed in the wells and an electric current is passed through it. DNA will try to run towards the positive end.

Shorter DNA segments can easily "squeeze" through the pores of the gel, while longer DNA segments require more "squeezing" to move down the gel. Band X in this figure is the short DNA segment as it moves through the lane at a faster rate and reaches much farther than the longer DNA segments.

Thus, smallest fragment of DNA that traveled the fastest. So, the correct option is (C).
