What is the advantage/disadvantage of having an O type blood group? Explain your answer in a hospital situation.
Answer:
O: Type O individuals can donate blood to anyone, because their blood has no antigens. However, they can only receive blood from other type O individuals (because blood with any antigens is seen as foreign).

How does the position of Earth and its orbit affect climate change?
Answer:
The Earth's orbit around the Sun is an ellipse, but it does change shape. ... At other times, the ellipse is more pronounced so that the Earth moves closer and further away from the Sun as it orbits. When the Earth is closer to the Sun our climate is warmer and this cycle also affects the length of the seasons.
Fenómeno que consiste na combustão de grandes áreas florestais e conduz à libertação de grandes quantidades de CO2 para a atmosfera.
Answer:
Wildfires.
Explanation:
Wildfires is the phenomenon that causes combustion of large forest areas and leads to the release of large amounts of CO2 into the atmosphere. Wildfire occurs naturally as well as carelessness of humans that leads to the destruction of large area of forest and the habitat of wild animals also destroyed which compels them to migrate from that region. This wildfires produced high amount of carbondioxide gas in the atmosphere that is the main cause of air pollution.

4. Cross a white bull with a white cow. Show the Punnett Square:
% Red Cow
% Roan Cow
% White Cow
Answer:
100% white cow
Explanation:
This question involves a single gene coding for skin color in cattle. The allele for red color (R) is codominant with the allele for white color (r). Hence, the roan cattle (Rr) will possess both red and white coloration.
According to this question, a white bull (rr) is crossed with a white cow (rr). Each parent will produce the "r" gamete, which when used in a punnet square will produce all WHITE COWS i.e 100% white cows. See punnet square attached.
Answer:
white cow
Explanation:
Is this correct guys?

Explain why hormone-producing cells are always located in close proximity to
capillaries.
Answer:
Hormone Signaling The hormones then diffuse to the bloodstream via capillaries and are transported to the target cells through the circulatory system. This allows hormones to affect tissues and organs far from the site of production or to apply systemic effects to the whole body.

Explanation:
A typical virus is made up of 2 parts. Check all that apply.
A) Golgi Body
B) Nuclear envelope
C) Nucleic Acid
D) Capsid
Answer:
C) Nucleic Acid
D) Capsid
Explanation:
A virus is structure that is dependent on a living host to replicate itself. Viruses are majorly pathogenic in nature and have a structure that is made up of two parts namely: nucleic acid and capsid.
The nucleic acid, which can either be RNA or DNA holds the genetic information of the virus while the capsid is a protein coat that enclosed and protects the virus' genetic material. The capsid is also used during the infection life cycle of a virus where it helps the virus to attach to receptor cells on the host's cell membrane.

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 stores and delivers nutrients throughout the cell and transports waste to the cell membrane
[tex] \huge \sf \star{Answer} \star[/tex]
Vacuoles store water, food, and waste. The endoplasmic reticulum (ER) is a series of tunnels throughout the cytoplasm. They transport proteins from one part of the cell to another. Ribosomes are the protein factories of the cell.
Hope it helps uh...The organelle that is responsible for storing and transporting nutrients through the cells is Vacuoles.
Vacuoles are also know as storage containers, they act as a storage organ in the body. This storage organ helps to transport food substances /molecules in the cell. Vacuoles are composed of enzymes, they help to hold water an food molecules. Vacuoles also help to remove waste substances that are harmful to the body.
The vacuole helps to keep balance in the body as they help to keep useful molecules and also get rid of waste substances.

Why might walking across rocks in shallow creek hurt your feet more than the same rocks would if you were in deeper water

Explanation:
Why do deserts tend to form on land at latitudes of 20-30 degrees north and south?
Answer:
Deserts can form even on tropical coasts beside cold ocean currents, such as the west coast of South America. The currents cool the air, which then rises and warms as it moves over land, drawing up moisture that is later precipitated as the air moves farther inland.
Which of the following would cause an error in DNA replication?
A. DNA polymerase pairing A with G
B. DNA ligase connecting chunks of DNA
C. Helicase making a replication fork
D. DNA polymerase checking the DNA
Answer:
A. DNA polymerase pairing A with G
Explanation:
Adenine (A) always pairs with thymine (T), and cytosine (C) always pairs with guanine (G).
DNA polymerase pairing A with G would cause an error in DNA replication. The correct option is A.
An error in DNA replication occurs when an incorrect nucleotide is inserted during the replication process.
DNA polymerase is responsible for synthesizing a new DNA strand by adding complementary nucleotides to the existing template strand.
It ensures the accuracy of replication by matching each nucleotide with its complementary partner (A with T and G with C).
If DNA polymerase pairs A with G instead of A with T, it results in a mismatched base pair.
This is considered an error in DNA replication since it introduces a mutation in the newly synthesized DNA strand.
The fidelity of DNA replication relies on the correct base pairing and proofreading mechanisms of DNA polymerase to minimize errors and maintain the integrity of the genetic information.
Thus, the correct option is A.

what effect does pH of water have on radish seed germination?
Explanation:
High pH negatively affected the germination rate of seeds from most species, but had no effect on the per cent germination of any of the species. The higher concentration of the nutritious solutions affected negatively the germination level and rate.
Answer:
A radish seed has a high percentage of germination in PH's 4-12 and a very low percentage of germination in PH 1-3 and PH 13-14.

• sexual reproduction
• diploid
• unique daughter cells
• gametes
• meiosis
• unique
• haploid
• zygote
• identical daughter cells
• mitosis
Answer:
Meiosis is a process in which sex cells, also known as gametes are made. Meiosis is different from mitosis in a lot of ways, one being that mitosis creates identical daughter cells and meiosis creates unique daughter cells. Meiosis is important because it allow for the creation of a meiosis nucleus. Cells produced by meiosis will be used in haploid, where each member of the next generation is genetically unique.
Cells produced in sexual reproduction will have half of the genetic information of body cells and will be genetically unique. This is necessary because when a sperm and an egg fuse together in sexual reproduction. They form a zygote: the first body of a new individual.
The new individual will now have cells that are diploid, meaning they have two sets of chromosomes. They zygote will have to do a lot of mitosis allowing it to grow quickly and ensure that all of its cells are genetically unique.
