help me please, i need complete sentences
Answer:
Look below
Explanation:
(A) A fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing organic molecules originating in ancient photosynthesis that release energy in combustion
(B) After millions of years underground, the compounds that make up plankton and plants turn into fossil fuels. Plankton decomposes into natural gas and oil, while plants become coal. Today, humans extract these resources through coal mining and the drilling of oil and gas wells on land and offshore.
(C) These non-renewable fuels, which include coal, oil, and natural gas, supply about 80 percent of the world's energy. They provide electricity, heat, and transportation, while also feeding the processes that make a huge range of products, from steel to plastics.

11. Question: Imagine 20 babies were born. 10 had blue eyes, and 10 had brown eyes. What traits do their parents probably have?
Answer:
The correct answer is - brown heterozygous Bb and blue eye bb.
Explanation:
In the provided question it is given that there are 20 babies born, 10 babies had blue eyes and 10 had brown eyes. As it is known that brown eyes are dominant over blue eyes, therefore, on the basis of this we can say that all blue-eyed babies have a bb genotype and as brown eyes are dominant traits babies must have at least one copy of the B allele which represents brown eye trait.
case1:
Parent 1 : bb
parent 2: BB
B B
b Bb Bb
b Bb Bb
there are 100% brown eye offspring so this is not the case
case 2:
Parent 1 : bb
parent 2: Bb
B b
b Bb bb
b Bb bb
here, 50% brown eyes and 50% blue eyes offspring produced thus, the parent trait will be brown heterozygous and blue eye.
The p53 gene is important to the cell cycle in G1 and G2, and cancer. What happens to the cell cycle when a mutation occurs in the p53 gene?
(please no links!!)
Answer:
PFFT this might help? sorry if not mate
Explanation:
Cell cycle checkpoint controls play a major role in preventing the development of cancer [see Sherr, 1994, for a more detailed discussion]. Major checkpoints occur at the G1 to S phase transition and at the G2 to M phase transitions. Cancer is a genetic disease that arises from defects in growth-promoting oncogenes and growth-suppressing tumor suppressor genes. The p53 tumor suppressor protein plays a role in both the G1/S phase and G2/M phase checkpoints. The mechanism for this activity at the G1/S phase checkpoint is well understood, but its mechanism of action at the G2/M phase checkpoint remains to be elucidated. The p53 protein is thought to prevent chromosomal replication specifically during the cell cycle if DNA damage is present. In addition, p53 can induce a type of programmed cell death, or apoptosis, under certain circumstances. The general goal of p53 appears to be the prevention of cell propagation if mutations are present. The p53 protein acts as a transcription factor by binding to certain specific genes and regulating their expression. One of these, WAF1 or Cip1, is activated by p53 and is an essential downstream mediator of p53-dependent G1/S phase checkpoint control. The function of p53 can be suppressed by another gene, MDM2, which is overexpressed in certain tumorigenic mouse cells and binds to p53 protein, thus inhibiting its transcriptional activation function. Other cellular proteins have been found to bind to p53, but the significance of the associations is not completely understood in all cases. The large number of human cancers in which the p53 gene is altered makes this gene a good candidate for cancer screening approaches.
Differentiate the pH conditions of the stomach and intestine and how does it help in the digestion of food.
i will mark u as brainliest if u answer
Answer:
pH of stomach is more acidic ranging from 1.5 to 3.5 meanwhile intestine is more on the neutral side ranging from 6 to 7.4
Explanation:
as far as it is concerned about digestion relation between the two stomach and intestine is that stomach has more acidic pH because most of the the digestion occurs in stomach. the more acidic ,the more quickly food will be broken down to essentials .like an upset stomach as it overdoes the digestion as for the intestine it is mainly responsible for absorption of already digested food..
PLEASE HELP WILL GIVE BRAINLIST!!!! Write a hypothesis to describe the relationship between earthquakes and tsunamis.
Answer:
Hypothesis: Earthquakes and tsunamis are caused by tectonic plates in the Earth's crust. When the crust moves, they occur, depending on the location of the crust.
Answer:
Most times a earthquake is what causes a tsunami, such as a deep ocean earthquake causing a tsunami to form. Most tsunamis are formed that way because deep ocean earthquakes create so much force.

Choose the correct connective tissue.
1)Bone to bone
2)Muscle to muscle
-ligament
-tendon
Explanation:
A tendon is a fibrous connective tissue which attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure. A ligament is a fibrous connective tissue which attaches bone to bone, and usually serves to hold structures together and keep them stable.
A tendon is a fibrous connective tissue which attaches muscle to bone.
A ligament is a fibrous connective tissue which attaches bone to bone.
What is tendons and its function?
A tendon is a cord of strong, flexible tissue, similar to a rope. Tendons connect your muscles to your bones. Tendons let us move our limbs. They also help prevent muscle injury by absorbing some of the impact your muscles take when you run, jump or do other movements.
What is ligament and its function?
Ligaments often connect two bones together, particularly in the joints: Like strong, firmly attached straps or ropes, they stabilize the joint or hold the ends of two bones together. This ensures that the bones in the joint don't twist too much or move too far apart and become dislocated.

describe one structural and one behavioural adaptation of humans for retaining heat in cold environments
Answer:
Water based fluid
Explanation:
The internal environment consists of water based fluid in which the cells of the body present. A fluid called interstitial fluid or tissue fluid bathes the cells and provides essential nutrients to the cell. The human skin has fatty layers that helps to maintain internal heat which is produced by the body when the outside environment is cold. When there is cold in the environment, people lives in warm shelters and wear warm clothes in order reduce the impact of cold environment.

When a stream's velocity decreases from 300 to 200 centimeters per second, which size sediment will be deposited?
Middle size sediment will be deposited on the ground when the speed of flowing water decreases.
Deposition of sedimentsWhen a stream's velocity decreases from 300 to 200 centimeters per second, the middle size sediment will be deposited because of the lowering velocity of the stream. Big size sediments hardly move by the water of the stream.
While on the other hand, middle and small sized sediments easily moved by the flowing water due to their light weight so we can conclude that middle size sediment will be deposited on the ground when the speed of flowing water decreases.

Are Fungi beneficial or harmful? Explain
Answer:
Honestly it depends...
Explanation:
I would say overall fungi are beneficial because they feed on dead organic matter. They recycle most of the carbon and release nutrients to be used by other organisms. They are also used for medicinal purposes. Not to mention yeast is a fungus and bread is yummy.
But certain fungi are deadly if ingested or linked to plant and human diseases. Also mold is a fungus and nobody likes mold.
the length of bamboo grows much faster than that of thickness why?
Using a slow- and fast-growing variant of bamboo, Wei and colleagues looked at cell division, growth, and gene expression (through transcriptomics, which measures all the genes being expressed by an individual) to discover which genes may be responsible for fast growth in bamboo. They found that the slow-growing variant had reduced expression of genes relating to cell wall construction, the plant hormone auxin (important for cell growth and cell division), and had irregular cell growth and cell walls. Wei and colleagues suggest that a reduced ability to produce and perceive auxin, combined with a weakened cell wall, are responsible for the slow growth seen in the bamboo variant.
