Answer:
Explanation:
For the first paragraph
1) The only experimental group is the group that took the supplement of 3000 mg. Experimental groups are groups that receive treatment during the course of an experiment. The treatment in this experiment is the nutritional supplement and group A was the only group that received that hence the correct option is A.
2) To have confidence in the result, it will be important to note if there were volunteers who had cold at the beginning of the experiment. Because if there were volunteers who had cold at the beginning of the experiment and were part of the experimental group, that could mean those volunteers didn't respond to the treatment because of underlying health condition which could be the cause of there own cold and might have to be treated based on the underlying condition thus negating the aim of the experiment which was to treat cold and not any underlying health condition. Hence, the correct option here is A
For the second paragraph
3) Since the only living property that the robot has according to the passage is movement then option A is the correct answer. There is no evidence from the passage that the robot can derive nutrition from food source from the passage. Also reproduction as a living property must be undertaken by the individual living organism in question; here researchers are the ones undertaken the reproduction and thus is not the property of the robot. Also, there is no evidence from the passage that the robot has fibroblasts.
4) The correct option here is B. Emergent properties of cells are collective properties that convey a particular attribute that cannot be achieved individually. The question says the cardiac cells will have to come together to cause the attribute of movement that cannot be achieved individually
NEED THIS ASAP!!!! Define: Meiosis, Sister chromosomes, homologous chromosomes
Answer:
meiosis- a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.
sister chromosomes- A sister chromatid refers to the identical copies (chromatids) formed by the DNA replication of a chromosome, with both copies joined together by a common centromere.
homologous chromosomes- Homologous chromosomes are two pieces of DNA within a diploid organism which carry the same genes, one from each parental source. Each parent provides the same 23 chromosomes, which encode the same genes.
Answer:
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females. ... These four daughter cells only have half the number of chromosome
A sister chromatid refers to the identical copies formed by the DNA replication of a chromosome, with both copies joined together by a common centromere. In other words, a sister chromatid may also be said to be 'one-half' of the duplicated chromosome. A pair of sister chromatids is called a dyad
homology is similarity due to shared ancestry between a pair of structures or genes in different taxa.
Chromosomes are the things that make organisms what they are. They carry all of the information used to help a cell grow, thrive, and reproduce. Chromosomes are made up of DNA. Segments of DNA in specific patterns are called genes. You will find the chromosomes and genetic material in the nucleus of a cell.

For which of the following problems would a crop rotation of various grains and legumes be an appropriate solution?
I. The nutrients in the soil on a farm are being depleted.
II. Over-irrigation is waterlogging the soil on a farm.
III. A particular kind of pest is infesting the soil on a farm.
II only
III only
I and II only
I and III only
Answer:
I and III only
Explanation:
Crop rotation is a farm practice that involves cultivating different species of crops on the same land at different seasons. In other words, the different crops are rotated. Crop rotation is done for various reasons including; improvement of soil fertility, pest and disease control etc.
In this case, a crop rotation of various grains and legumes would be an appropriate solution for the following problems:
- The nutrients in the soil on a farm are being depleted: Legumes are known to be rich in nitrogen and hence add nitrogen to the soil due to the nitrogen-fixing microbes in their roots. Hence, rotating between grains and legumes can help return the depleted nutrients (by grains) to the soil.
- A particular kind of pest is infesting the soil on a farm: Most pests are usually crop-specific, hence, planting only one type of crop can make that soil be infested with a particular kind of pest. However, rotating between crops such as grains and legumes can make a particular pests become scarce or less populated.

Which process can occur in both mitosis and meiosis?
A. Crossing over
B. Gene mutation
C. Independent assortment
D. Fertilization
Answer:
B. Gene mutation
Explanation:
Stable changes in the DNA strand that are capable of being inherited are known as mutations.
The truly transcendent mutations for the offspring are those that are present or occur in germ cells (ovules and sperm).
The mutations that occur than can lead to small changes, large changes (causing disease: pathogenic mutations), or be silent.
Mitosis and meiosis can both be influenced by mutation of genes.
Gene mutation refers to a change to the DNA sequence of organisms. Mutation can be of different kinds, including deletion, substitution, or insertion of base sequence into genes.
Gene mutation can happen during, before, or even after meiosis and mitosis.

Explain how salinity can make water move
Answer:
Through concentration gradients and a semi-permeable membrane.
Explanation:
Imagine a semi-permeable membrane splitting a beaker into two sides which only water can pass through and salt cannot.
One side is filled with much more salty water than the other. (the saltiness, not the amount of water).
Since the salt cannot pass through the membrane, one side's salt is much more concentrated than the other.
In an effort to restore equilibrium, more water passes to the saltier side to balance out the ratio of water : salt.
Since one side has more salt, more water is needed to balance that out, and hence water moves towards the saltier side.

Once blood tonicity is negatively impacted, can the consequences be reversed?
Answer:
No.
Explanation:
Once blood tonicity is negatively impacted, the consequences can't be reversed because this tonicity permanently damaged the cell. For example, in hypotonic solution, If the water continues to move into the cell due to high solute concentration, it can damaged the cell membrane, the cell bursts and dies. But it can be reversed if the cell loses its water and become shrink in hypertonic solution and regain its original size by normalizing the water level.

Seeds that are planted upside down are still able to grow into mature plants. Which explanation
best explains this phenomenon (a)The roots change into branches in the branches turn to roots(b) The roots grow towards the force of gravity and the stem goes away(c)The plant will become a smaller version of a mature plant(d) roots always grow toward the dark and the stem grows toward the light
The explanation that best explains this phenomenon is: the roots grow towards the force of gravity and the stem goes away
WHAT IS GEOTROPISM?The parts of a plant can be divided into shoot and roots. The root of the plant is the part that grows below the ground surface in order to anchor the plant.
When a seed germinates, the root part of that seed grows towards gravity i.e exhibits geotropism while the shoot part grows away from gravity i.e. upwards.
Hence, if a seed is planted upside down, it will still grow into an erect mature plant because the root will grow downwards towards gravity (positive geotropism) while the stem grows upward away from gravity (negative geotropism).

What do you think the following do when consumed? Protein, lipid,
carbohydrate, nucleic acid.
Answer:
The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins. A related type of nucleic acid, called ribonucleic acid (RNA), comes in different molecular forms that participate in protein synthesis.
Carbs Provide Your Body With Energy
Glucose in the blood is taken up into your body's cells and used to produce a fuel molecule called adenosine triphosphate (ATP) through a series of complex processes known as cellular respiration. Cells can then use ATP to power a variety of metabolic tasks.
Functions of Lipids in the Body: Storing Energy
The excess energy from the food we eat is digested and incorporated into adipose tissue, or fatty tissue.
Protein makes up the building blocks of organs, muscles, skin, and hormones. Your body needs protein to maintain and repair tissues. Meanwhile, children need it for growth. Studies show that eating protein can also help you lose weight and belly fat while increasing your muscle mass and strength.
