Answer:
In metaphase I, the tetrads line themselves up at the metaphase plate and homologous pairs orient themselves randomly. In anaphase I, centromeres break down and homologous chromosomes separate. In telophase I, chromosomes move to opposite poles; during cytokinesis the cell separates into two haploid cells.

Full moonA Full moon occurs when the moon moves from its new moon position by 180°. At this new position, the sun ( light source ) ,earth and the moon forms a straight line.
During full moon the moon is completely illuminated when viewed from the Earth's position as well.
Hence we can conclude that the diagram that represents the modelling of a full moon is Diagram 4

In a paragraph below, explain the definition of biotechnology and cite at least three examples of it. Also, explain why it is a controversial field of science.
Answer:
Biotechnology is a branch of science that deals with technology by utilizes biological systems, living organisms, or parts of this to develop or create products with the goal of human welfare.
During brewing and baking bread yeast are used to produce alcohol are examples of processes that fall within the concept of biotechnology, Genetically modified orgnisms and crops are also product of the biotechnology. The insulin production also an example of this process.
People consider use of biotechnology unethical to produce genetically modified organisms or crops and cloning is considered as against the law of nature.

What happens to chromosomes when an ovum and a sperm meet at fertilisation
Answer: When egg and sperm cells combine in fertilizations, they merge the two sets of chromosomes, ending up with 46 chromosomes in total. The maternal chromosomes from the egg cell and the paternal chromosomes from the sperm cell pair up. The resultant cell is called a zygote. Fertilization happens when a sperm cell successfully meets an egg cell in the fallopian tube. Once fertilization takes place, this newly fertilized cell is called a zygote. From here, the zygote will move down the fallopian tube and into the uterus. The zygote then burrows into the uterus lining.

What is the effect of an increased concentration of calcium ion in the sarcoplasm?
Answer:
When calcium concentration increases during depolarization, it shifts the conformation of troponin and tropomyosin, and actin is able to associate with myosin. As calcium is taken up again by the sarcoplasmic reticulum the muscle cell relaxes.
The effect that can be associated with increase in concentration of calcium ion in the sarcoplasm is :
Changing of shape and position of tropomyosin.
Can also cause muscles stiffness.
When the Ca2+ concentration become high in the sarcoplasm, there would be change in the position of tropomyosin as result of the binding effect of Ca2+ binds on troponin.Then the tropomyosin will be moved away from myosin binding sites on actin, then a cross bridge will be formedHowever, the effect if this on muscles is muscles stiffness.

Does the Second Amendment need to be "revisited" in 2021? yes and why?
I need help pleasee
Answer:
It needs to be revisited because of the random acts of violence that it enables.
Explanation:
People that have access to weapons of mass destruction use them to kill people for no reason. For example, the sandy hook shooting, the recent Stoneman Douglas shooting, and the Christchurch shooting. All these shootings could have been prevented if there was stronger gun control. If people did not have access to automatic firing machine guns, less people would have died.

what are the two main types of chemical bonds?
Answer:
Chemical bonds include covalent, polar covalent, and ionic bonds. Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds. Atoms with large differences in electronegativity transfer electrons to form ions. The ions then are attracted to each other.
Two of the strongest forms of chemical bond are the ionic and the covalent bonds. Chemical bonds form between two atoms, each with its own electron environment.
Hope it helps!!!
Answer:
the two main types of chemical bonds are:
ionic bonds and covalent bonds.
Which of the following is NOT an ethical concern raised by genetic engineering?
A. Genetically engineered bacteria cells can be used to clean up mining waste and for sewage treatment
B. Creating organisms that are not naturally occurring may disrupt the environment
C. The question may need to be "should we" manipulate genes of organisms instead of "can we".
D. Creating plants with new genes may trigger allergic reactions
Answer:
The Answer Is A.
Explanation:
If They Can Be Used For Cleaning Up Mining Waste And For Sewage Treatment, That Makes Them A Good Thing. So It Wouldn't Be A Concern. Hope This Helps.
Genetically engineered bacteria cells can be used to clean up mining waste and for sewage treatment, which is not an ethical concern raised by genetic engineering. So, the correct option is A.
What do you mean by Genetic engineering?Genetic engineering may be defined as a process that involves the manipulation of the genetic material of organisms with help of lab-based technologies.
Bacterial species produced by genetic engineering used in cleaning up mining waste and sewage treatment benefit the atmosphere by reducing the level of waste and toxic compounds from suuroundings. So, it is not a matter of ethical concern.
Therefore, the correct option for this question is A.

Which is the best explaination for how chemical energy is transferred with cells
Answer:
Inside the cell, each sugar molecule is broken down through a complex series of chemical reactions. As chemical energy is released from the bonds in the monosaccharide, it is harnessed to synthesize high-energy adenosine triphosphate (ATP) molecules. ATP is the primary energy currency of all cells.

The scientists notice that one measurement stands out.
How should the scientists best deal with this
measurement?
O accept it as true and use 85 micrometers in the data
when they find the average length
O accept it as true but say that it is the only cell that has
ever been that long
O consider that there was an error during measuring
and collect further data
O consider that it is possible but very unlikely for these
bacterial cells to be so long
Answer:
consider that there was an error during measuring
and collect further data
Explanation:
Human errors during observation are common, and although they should keep their minds open to the probability of it being longer, it is much more likely the researcher made a mistake, which they need to account for first.

Read the passage. Then explain the ways humans have influenced the traits in corn plants and the impacts each biotechnology has had.
Passage
Many of the types of corn found in grocery stores were originally bred for their taste and productivity. But these varieties are often threatened by pests. This makes it harder for farmers to produce enough corn.
Scientists have used genetic engineering to make GMO corn plants that are resistant to pests. In one type of GMO plant, they added genes from bacteria that live in soil. The genes let the GMO plants produce a bacterial protein that kills certain insects.
Answer:
It decreases cost of production on the crop as well as increase production.
Explanation:
It is a very efficient method to save a corn plant from the attack of bacteria. This method is used in almost each and every plant in order to make it resistance against harmful pests and microorganism. By using this technology, the cost of production on the growing of crop decreases which gives more profit to the farmers as well increase the overall productivity of that corn crop.
Answer:
One of the ways we have influenced the traits in corn is through selective breeding. We now have taller plants, and bigger ears of corn, that taste better. Another way we have influenced the traits is by modifying them to be pest resistant.

A baker activates yeast cells with hot water, and adds sugar as their source of food. As the yeast begin their metabolic processes, the bowl it is in is covered with plastic so that no oxygen can get to them. At this point, the yeast will __ *
1 point
a. produce far more ATP than is necessary in response to the lack of oxygen
b. continue to go through aerobic respiration if enough sugar is present
c. die since all living organisms need oxygen to survive.
d. perform anaerobic respiration in the absence of oxygen
Answer:
The correct answer would be - option D. perform anaerobic respiration in the absence of oxygen.
Explanation:
Yeast is a facultative anaerobic single-cell organism that can live without oxygen. If yeast cells did not get the oxygen they use anaerobic respiration to get the energy.
If the baker activates these cells and stops them to get oxygen the yeast cells have to switch to anaerobic respiration to survive and produces ethanol and releases carbon dioxide.
