Answer:
The overview of the problem concerned is listed below.
Explanation:
Mostly during Paleocene Eocene Temperature Optimum, we consider temperate vegetation momentarily relocated towards the poles whenever global average surface temperature jumped, bug harvesting temporarily escalated, as well as coral reef crashed.The level of variations in climate or temperature was as sluggish as it is today, which suggests that such past occurrences are likely to overestimate the effects of rising temperatures nowadays.Increase occur in the insect's population due to increase occur in global surface temperature.
During the Paleocene-Eocene Thermal Maximum, when global surface temperatures increase, we observe temperate forests having more population of insects due to favourable temperature for the growth of insects.
The productivity and distribution of forests could be affected due to change occur in the temperature, precipitation and the amount of carbon dioxide in the air. As the temperature increases the population of insects also increases which leads to increase in biodiversity of forest so we can conclude that increase occur in the insect's population due to increase occur in global surface temperature.

Which statement correctly compares the "Analysis" and "Conclusion" sections of a lab report?
Answer:
Hello. You did not enter the answer options, but I can help you by stating that the correct comparison between "analyze" and "conclusion" is one that shows that "Analysis" is able to compare specific research data, while "conclusion" is able to suggest additional research to arrive at more concrete data.
Explanation:
In a scientific research, the "Analysis" section is where the specific research data and the interactions and information that can be extracted from them are analyzed, in a succinct and explanatory way. This section is very important to present how these data were acquired and how they work within the theme developed in the research.
The section called "conclusion", in turn, presents the section where the research will conclude the established theme, showing an affirmation discovered through the research or suggesting additional research that will help to establish an efficient conclusion.
You perform a test cross of the dihybrid AaBb and score the phenotypes of 1000 progeny. Assuming independent assortment, how many of the progeny do you expect to display the dominant phenotype for both the A and B genes?
Answer:
4
Explanation:
The number of progeny expected to display the dominant phenotype for both the A and B genes should be 4.
A test cross usually involves crossing an individual whose zygosity is in doubt with an individual that is recessive for both alleles so as to ascertain the zygosity of the former. Hence, for a test cross involving AaBb:
AaBb x aabb
Progeny:
4 AaBb
4 Aabb
4 aaBb
4 aabb
Therefore, the number of progeny expected to display the dominant phenotype for both the A and B genes is 4.
Some people use the terms "cell cycle" and "mitosis" as if they were the same thing. Which of these best describes why they are not the same?
a. the cell cycle is just a stage of mitosis
b. mitosis and the cell cycle are different types of cell division that occur in different of cells in a multicellular organism
c. mitosis is a sequence of events within the cell cycle that separates the genetic material
d. mitosis is a type of cell division that occurs in eukaryots and the cell cycle takes place in prokaryots
Answer: C. Cells in meiosis have unique genetic information
Explanation: Meiosis is the cell division that forms four daughter cells from one parent cell. It includes two successive divisions called as meiosis I and meiosis II. Crossing over during prophase I of meiosis I imparts new gene combinations to the daughter cells of meiosis. Hence, daughter cells formed by the end of meiosis have some new gene combinations, that is, unique genetic information.

Biologists designed an experiment to test the effects of compost on the development of root crops
Answer:
The crop has good yield because Compost has a good effect on root crops.
Explanation:
Compost has a great effect on the development of root crops such as onion, potato, garlic and ginger etc. Compost provide nutrients to these crops as well as soften the soil due to which they grow rapidly. It also improved ventilation, soil structure and soil texture which is very necessary for the crop. Due to ventilation, oxygen gas is available to the roots which increases growth and yield of these crops. Compost also retain water and nutrients so they are available to the roots. So those plots where compost is applied observed increase in yield as compared to other plots.
Why photosynthesis can't take place in such an environment , where there is no oxygen..? And exactly why trees need oxygen for photosynthesis ?
Answer:
Photosynthesis is a chemical process that leads to the release of oxygen as a by-product and is necessary for cellular respiration
Explanation:
The plants produce or make oxygen form the wastes of starch, sunlight carbon dioxide, and water. In order to burn the sugar that is stored in the plants, it needs to have sunlight which requires oxygen. As the break down of sugar C6 H12 O6 to CO2 and H2O needs O2 to do it. Which is called cellular respiration. This is also stated by the first law of thermodynamics that energy cannot be created and neither destroyed but transforms itself. Photosynthesis is the chemical process that is used to convert this chemical energy which makes carbon and water into glucose and oxygen is released as a by-product.Jeremiah is on a school trip to a forest preserve.

A graduate student studying biology at the University of Nebraska has identified a new species of spider found only in Eastern Nebraska around Omaha. The graduate student determines that the spider has six homologous pairs of chromosomes. How many chromosomes would a cell in that spider have during metaphase of mitosis?
Answer:
12 chromosomes
Explanation:
Mitosis is a type of cell division that involves the formation of two genetically identical daughter cells. The two daughter cells are genetically identical in the sense that they contain the same number of chromosomes as the parent cell. Mitosis involves four stages namely: Prophase, Metaphase, Anaphase and Telophase.
In the metaphase stage as stated in this question, homologous chromosomes align at the equator of the cell called cell plate, before each chromatids are pulled apart by microtubules at the Anaphase stage.
According to the question, the spider being worked on has 6 pairs of chromosomes, which will align at the cell's equator during metaphase stage of mitosis. Since the replicated chromosomes (chromatids) are yet to separate to opposite poles of the cell, the cell will still contain 12 chromosomes at the metaphase stage.
N.B: Each chromosome contains 2 chromatids or replicated chromosome, which will be separated at the Anaphase stage. Each chromatid will be an individual chromosome after cytokinesis.

How does the movement of particles of matter change when temperature increases?
Decreases
Increases
Increases then decreases
Does not change
Answer:
Increases
Explanation:
The movement of particles of the matter increases with the increase in temperature.
The particles gain kinetic energy with increasing temperature and move in faster rate.
For example: When we blow a balloon with our mouth, we increases the temperature inside the balloon, the particles in the balloon gain kinetic energy that leads to the faster movement of gas particles in the balloon and they collide with each other and surface of balloon, after a peak the balloon get burst because of high kinetic energy and high collision.
Hence, the correct answer is "increases".

Answer:
The correct answer is intragenic suppressor mutation.
Explanation:
A suppressor mutation partially or completely converses the effects of a different mutation. A suppressor mutation is of two kinds, that is, an intragenic suppressor and an intergenic suppressor. An intragenic suppressor converses the influence of a mutation at a distinct site in a similar gene.
On the other hand, an intergenic suppressor converses the influence of a mutation at a distinct locus of the gene. It is the intragenic suppressor mutation, which takes place in a similar gene where the occurrence of the first mutation had taken place. Therefore, the mutation, which hides the influence of another mutation at a location, which is different from the location of the original mutation, but taking place in a similar gene can be illustrated as the intragenic suppressor mutation.

Filtration is not a function of digestive system because it play a major role in circulatory system which help in movement of solutes out of the capillary into interstitial fluid by separating the bigger particles from the smaller particles, filtering out nitrogenous waste and regulating salt concentration .
Outside the lining of the alveolus is blood, which is at a gauge pressure of 5 mmHg, while air is contained inside the alveolus. What is the absolute pressure inside the alveolus
Answer:
765 mmHg
Explanation:
The gauge pressure = 5 mmHg
To get the absolute pressure we use the relationship
[tex]P_{ab}= P_{g}+ P_{atm}[/tex]
where [tex]P_{ab}[/tex] is the absolute pressure = ?
[tex]P_{g}[/tex] is the gauge pressure = 5 mmHg
[tex]P_{atm}[/tex] = atmospheric pressure = 760 mmHg
substituting, we have
[tex]P_{ab}[/tex] = 5 mmHg + 760 mmHg = 765 mmHg
5.Do the differentiated teeth of the dolphin have specialized functions like our teeth and most other mammals
Answer and Explanation:
Dolphins are homodont. This means that all their teeth are all equal. They do not differentiate between each other as the human´s teeth or other mammal´s teeth.
Dolphins have different feeding strategies according to the species. They might be suction feeders, or they might catch their prey using the jow and mandible occlusion strenth.
Dolphins that catch their prey by using their jow and mandible do not chew, so they use teeth mostly to catch their prey and manipulate them before swallowing them. This is why they do not need differentiated teeth. Because they just use them to catch and manipulate.
Those dolphin species that are suction feeders do not need teeth to catch their prey because they just suck them. Most of these species only have a few teeth, mostly in their jows. These teeth are used for fighting with other individuals. Inter- and intra-specific fights among animals of the same gender and age are very common. It is believed that as these species do not need teeth for catching their prey, they evolved loosing most of them but those needed during confrontations. This is the case of Grampus griseus, Risso´s Dolphin, that only have 5 to 7 teeth in their jows.

Choose a strategy to clone genes known only by a mutant phenotype in organisms with highly efficient transformation procedures and relatively small genomes.
a. cloning by complementation
b. direct sequencing of the mutant genome
c. PCR of the gene and transformation of an organism
d. cloning using a specific cloning vector
Answer:
Option a (cloning by complementation) `would be the correct choice.
Explanation:
In species containing extremely efficient transforming techniques as well as comparatively small genomes, cloning by rearrangement testing is performed to clone gene products mostly by a mutated gene as the rearrangement test was being used to detect mutations.This strategy for cloning through mechanism begins with identifying another yeast mutant that affects something like a plasmid representing a cloned genetic material.The other options in question aren't relevant to the particular circumstance. Therefore the answer to the above seems to be the right one.

Explanation:
Answer:
The phagocytes cell in the skin are the monocytes, macrophages, neutrophils, tissue dendritic cells and mast cells. One litre of human blood contains about six billion phagocytes.
When pathogens are detected, the immune system produces millions of white blood cells, which fight the infection. Blood vessels near the wound expand, and white blood cells move from the vessels to enter the infected tissues. Many of these white blood cells are phagocytes which engulf and destroy bacteria.
