If you wanted to study the effects of soil moisture and light intensity on the growth of soybeans and required a high ability to regulate these independent variables, what type of experiment would you choose?A. Laboratory experiment.
B. Field experiment.
C. Natural experiment.
D. Reference experiment.

Answers

Answer:

A

Explanation:

The correct answer would laboratory experiment.

In the laboratory, variables can be controlled as much as possible using relevant equipment unlike in natural habitats or field experiments. For example, the amount of water that each plant would receive can be measured using measuring cylinders and the time they are applied can also be fixed.

Field and natural experiments require that experimental procedures are carried out in the field under natural conditions. Consequently, variables such as the amount of moisture that gets into the soil or the amount of light a plant will receive will be extremely difficult to control. Precipitation time and the duration of light can also not be controlled.

The correct option is, therefore, A.

Which of the following does not explain why if two people are exposed to the same high stress causing conditions, there is a likelihood that they will not be affected the same way? A) the two have different lifestyles B) some people are not at all affected by stress C) gene-environment interactions may affect the level of depression D) people react differently to stress E) presence of a specific gene variation

Answers

Answer:

Probably B

Explanation:

They all explain it, honestly, but B sounds the least like an answer they would accept as true. It's also kind of sus that they have 2 different answers about reacting differently to stress, and B is definitely the least likely of the two to be correct.

Explanation:

Answer:

Explanation:

In humans, there is a dominant allele that causes vitiligo, where small-unpigmented spots appear on the body. Also, there is a recessive allele for another gene that caus- es albinism, which causes the entire body to be unpig- mented. Vitiligo cannot be seen in albinos. A man with vitiligo had an albino mother and normal father. If the man has a child by a phenotypically normal skinned woman who had an albino father, what is the probability of having a phenotypically normal child

Answers

Answer:

probability = 0

Explanation:

The probability of having a phenotypically normal child is = 0

This is because since the Paul has Vitiligo and the vitiligo ( allele ) is a dominant allele and hence the allele will be passed onto the Child ruling out the chance of the couple having a phenotypically normal child

Conservation is the careful protection and preservation of the environment. Option C is correct.

The activity of man that leads to the deforestation of the forest lands is deforestation. Hence the option B is correct. The conservation of the earth's resources depends on many factors but it does not on buying products made from animals. Hence the option C is correct. The factors that destroy the coral reefs are B and C that are waste dumping and dynamite fishing. The ecological unit of the ecosystem includes the biotic and abiotic forms in order to interact with each other. Hence the option B is correct.

Sheep Brain Dissection Steps

Answers

Sheep brains, like other sheep organs, are much smaller than human brains, but have similar feature. They can be a valuable addition to your study of anatomy.

See for yourself what the cerebrum, cerebellum, spinal cord, gray and white matter, and other parts of the brain look like with this sheep brain dissection guide! Use this for a high school lab, or just look at the labeled images to get an idea of what the brain looks like.

You’ll need a preserved sheep brain for the dissection. Set the brain down so the flatter side, with the white spinal cord at one end, rests on the dissection pan. Notice that the brain has two halves, or hemispheres. Can you tell the difference between the cerebrum and the cerebellum? Do the ridges (called gyri) and grooves (sulci) in the tissue look different? How does the surface feel?

Turn the brain over. You’ll probably be able to identify the medulla, pons, midbrain, optic chiasm, and olfactory bulbs. Find the olfactory bulb on each hemisphere. These will be slightly smoother and a different shade than the tissue around them. The olfactory bulbs control the sense of smell. The nerves to the nose are no longer connected, but you can see nubby ends where they were. The nerves to your mouth and lower body are attached to the medulla; the nerves to your eyes are connected to the optic chiasm. Using a magnifying glass, see if you can find some of the nerve stubs.

Des a magnetic field flows though the inside of a magnet

Answers

Answer:

Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the magnet, toward the south pole of the magnet.

Explanation:

Answer:

However, the magnetic field lines do not just end at the tip of the magnet. They go right through it, so that inside the magnet the magnetic field points from the south pole to the north pole. Thus the magnetic field lines form a closed loop and do not have any ends.

As a plant grows, new root hair cells are formed from unspecialised cells.

How does an unspecialised cell become a new root hair cell?

Answers

Answer:

Root hairs appear in the root maturation zone and differentiate from unspecialised cells called trichoblasts.

Explanation:

Root hair arises as a small protrusion surrounded by a cell wall, they are found in the piliferous area; they can originate in unspecialised epidermal cells, in some called trichoblasts. The bump begins to elongate and moves away from the epidermis, forming root hair. The root hairs as they lengthen, it is seen that their content shows a polarized distribution, the apical part is constituted mainly by vesicles secreted by the Golgi apparatus that contain the precursors of the cell wall that are to be released by exocytosis. Trichoblasts can be arranged in different ways, there are roots where any of the cells that are part of the rhizodermis can give rise to a root hair. In other roots, trichoblasts and atricoblasts have been seen to be distinguished alternately along a row of cells.

The diagram models a hypothesis situation in which every location on earth would have 12 hour of daylight and 12 hours of darkness per day is earth orbit is perfect circle. Hence option B is correct.

What is hypothesis?

Hypothesis is defined as a concept or assumption put forth for the sake of discussion and examined to see if it might be true. A hypothesis is seen as a wise guess or prediction that points the researcher in the right path as they attempt to respond to the research topic.

Earth rotates on its axis, or turns, once every 24 hours, carrying us all along with it. When we are on the side of the Earth that faces the Sun, we experience daylight.  We are now on the side of the Earth that faces away from the Sun, and night has fallen.

Thus, the diagram models a hypothesis situation in which every location on earth would have 12 hour of daylight and 12 hours of darkness per day is earth orbit is perfect circle. Hence option B is correct.

The _____ strand of the opened DNA is easily replicated, but the _____ strand must be replicated in pieces because of its orientation.

a. bottom; top
b. lagging; leading
c. leading; lagging
d. top; bottom

Answers

Answer:

c. leading; lagging

Explanation:

This question s describing the process of DNA replication, which is the process by which DNA forms an identical copy of itself. The process of DNA replication is carried out majorly by an enzyme called DNA polymerase. After which the double stranded DNA has been unwound by DNA helicase, two single strands results.

One of these strands runs in the 3'-5' direction called LEADING STRAND while the other runs in the 5'-3' direction called LAGGING STRAND. However, because replication by DNA polymerase proceeds in the 5'-3' direction, the LEADING strand of the opened DNA is easily replicated, but the LAGGING strand must be replicated in pieces called OKAZAKI FRAGMENTS because of its orientation.
