A group of beetles live in forest with medium brown tree trunks where these beetles like to hide. Most of the beetles are medium brown, but about 10% are grey. This beetle species is often prey for large birds that live in the forest. A new coal fired power plant opens in the area and the trees become covered with a layer or grey ash. What do you predict will happen to this beetle population
Answer:
it will decrease with cause of power plant
Explanation:
Local factors are important for regulating blood flow to tissue capillary beds. For example, in skeletal muscle tissue that is actively contracting, levels of oxygen start to decrease as the oxygen is utilized, and levels of carbon dioxide increase as it is produced during cellular respiration. Decreasing levels of oxygen in the tissue cause the smooth muscle forming sphincters in arterioles to relax.
Answer:
true
Explanation:
In smooth muscle contraction, the sphincters relax in the face of the drop in partial tissue pressure of oxygen, and the increase in protons or positively charged hydrogen molecules. In this way, when the sphincter relaxes, the easier and faster contraction of an autonomous and simultaneous nature is conducted.
1. Why is California at hingher for earthquakes than North Dakota
Answer:
because California is located on the San Andreas Fault
Explanation:
California is one of the states that have higher seismic activity because it lies on an individual fault known as the San Andreas Fault. Faults are regions where two tectonic plates are moving with respect to one another, thereby they are prone to suffer earthquakes. The San Andreas Fault is a continental fault that extends approximately 800 miles (1,200 kilometers) through the US state. Conversely, earthquakes in North Dakota are uncommon because this state is located in the middle of a tectonic plate. The last earthquake in North Dakota had a magnitude of 3.3 (Richter Scale) and it happened almost 10 years ago (2012), in Williston.

Explanation:
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.
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.
Scientists believe that there are three jeans what contribute to skin color in humans.
Which of these best describes the inheritance pattern of skin color?
A. Multiple allele in which offspring recessive three allele from each parent.
B. Multiple allele in which offspring recessive three allele from only one parent.
C. Polygenic in which offspring recessive three allele from each parent.
D. Polygenic in which offspring recessive three allele from only one parent.
Answer:
C. Polygenic in which offspring receive three allele from each parent.
Explanation:
In genetics, a polygenic inheritance is an inheritance that involves more than one gene i.e. more than one gene controls a particular trait. This is the case of the skin color trait in humans, which is controlled by three genes.
However, since each gene contains two alleles, each parent will contribute three alleles for the three genes to the development of an offspring i.e. three alleles from the father and three from the mother will result in three genes in the offspring, each containing two alleles.

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.

What is climate change?Climate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, such as through variations in the solar cycle.
Due to global warming many species become vulnerable to climate change. One such species is polar bear. Polar bears live in arctic region and this region is getting warmer due to climate change. Warming of arctic region results into melting of sea ice.
Existence of sea ice is important for the survival of polar bears because seals are the main food of the polar bear and they hunt seals on the sea ice. Therefore, without sea ice, polar bears cannot hunt enough seals to eat thus, it will be difficult for them to survive.

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
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

Costa Rica, located in Central America, features a very high level of biodiversity due to its tropical climate and large range of habitats. As a result, Costa Rica has endless examples of population interactions lurking in its rain forests. Read about three of these interactions, and then complete the sentences that follow. SlothTickCoral snake Brown-throated sloths (Bradypus variegatus) are tree-dwelling mammals and one of the least active animals on earth. Sloths spend most of their time sleeping or eating young leaves from the trees they live in. The interaction between the sloths and the leaves they eat is an example of a relationship. In this example, sloths are that acquire their nutrients and energy from the they eat. The colors of coral snakes provide these animals with to avoid predation. Specifically, their coloration helps them . The interaction between the hosts and the ticks that live on them can be characterized as , because .
Answer:
The interaction between the sloths and the leaves they eat is an example of a predator-prey relationship. In this example, sloths are herbivores that acquire their nutrients and energy from the plants they eat. The colors of coral snakes provide these animals with mimicry to avoid predation. Specifically, their coloration helps them advertise their toxicity. The interaction between the hosts and the ticks that live on them can be characterized as parasitism, because one species feeds on the other.
Explanation:
Predator-prey relationships are those in which a specie feeds on another specie. The sloth is the predator that feeds on the leaves which are its prey. Herbivores feed on plants. Therefore, the sloth are rightly classified as herbivores.
Coral snakes are brightly colored with red, yellow, and black patches that warn potential predators of their toxicity. Ticks living on hosts are parasitic because the ticks feed on their host.

As a plant grows, new root hair cells are formed from unspecialised cells.
How does an unspecialised cell become a new root hair cell?
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.
Match each stem or root to its description.
