1. What do you know about gravity?
2. How could gravity affect the water cycle?
Explain your answer.''
Explanation:
What do you know about gravity?
ans:Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is an attraction that exists between all objects, everywhere in the universe. ... where G is called the Gravitational Constant.
How could gravity affect the water cycle?
ans:It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. ... Gravity pulls denser air and water downward, forcing less dense air and water to move upward. The warm water near the surface of the ocean heats up with sunlight and evaporates, keeping the water cycle in motion.

Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant
produced. THis is common in premature infants.
In healthy individuals, friction is a major factor affecting pulmonary ventilation
Answer: Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant produced. This is common in premature infants.
Explanation:
Infant Respiratory Distress Syndrome (RDS) occurs in new born infants whose lungs are unable to produce the enough surfactant to keep their lungs expanded which would enable them to breathe properly after delivery.
It is most common in premature infants because surfactant is produced in the third trimester of pregnancy so premature infants might not get the chance to produce enough before the are delivered. RDS needs to be treated as soon as possible or else a baby could suffer damage to the brain and other vital organs.
A student boiled a pot of water on the stove until there was nothing left. If he started with 100 grams of water, how many grams of water vapor did he produce?
Answer:
100 grams
Explanation:
If there is nothing left that means that all of the 100 grams have become water vapors
He produced 100 grams of water vapor in such a way that nothing was left, which means that all the water vapor of 100 grams has become.
What is Water vapor?Water vapor is also called aqueous vapor is defined as the gaseous phase of water which is a state of water within the hydrosphere. Water vapor can result from the evaporation or boiling of liquid water, or from the sublimation of ice that is transparent, as are most components of the atmosphere.
When water absorbs a sufficient amount of heat it becomes a gas known as water vapour, where the process is called evaporation. The water vapor (steam) mixes with the air and appears as water boils in a teapot and escapes into the air.
Thus, the student produced 100 grams of water vapor in such a way that nothing was left, which means that all the water vapor of 100 grams has become.

Homeostasis is the ability of the body to maintain internal balance despite changing external conditions. How does the respiratory system help maintain homeostasis? The respiratory system helps release hormones to control body processes. The respiratory system helps release unwanted heat and water from the body, The respiratory system produces white blood cells that kill disease causing organisms. The respiratory system releases enzymes that help in the break down of food.
Answer:
b on edge
Explanation:
its right
The respiratory system helps release unwanted heat and water from the body, maintaining homeostasis.
What is homeostasis?" A state of balance among all the body systems needed for the body to survive and function correctly."How respiratory system maintain homeostasis?Respiratory system helps to remove carbon dioxide and excess heat from our body and maintains our blood pH.During respiration, carbon dioxide reacts with water to form a carbonic acid in presence of enzyme carbonic anhydrase. It further dissociates into bicarbonate and H+ ions. This reaction are in equilibriumWhen the level of H+ ions increases, the pH level increases. This will signal respiratory system to release more carbon dioxide. This will result in formation of carbon dioxide and decrease level of H+ ions which will result in increase blood pH.When we breathe out, the moisture from the tissue are also expelled.Hence, the respiratory system helps release unwanted heat and water from the body.

Seed size in a plant is a polygenic characteristic. A grower crosses two pure-breeding varieties of the plant and measures seed size in the F1 progeny. She then backcrosses the F1 plants to one of the parental varieties and measures seed size in the backcross progeny. The grower finds that seed size in the backcross progeny has a higher variance that does seed size in the F1 progeny. Explain why the backcross progeny are more variable.
Answer:
The F1 progeny is completely heterozygous for the loci of interest since they were obtained by mating between two pure-breeding plant lines. In the next generation, the backcross progeny will have homo-zygous individuals and therefore they will be more variable, resulting from meiosis in F1 hybrids
Explanation:
An F1 resulting from the cross between two pure-breeding plant lines will produce all hybrid individuals, all of them genetically (and phenotypically) identical. Meiosis in F1 hybrids is well known to produce homo-zygous genotypes and thus increases genetic diversity in progeny. For instance, for a single locus, the expected ratio of genotypes obtained from crossing two heterozygous parents is 1:2:1, i.e., one homo-zigous dominant individual, two heterozygous individuals (genetically identical to the parents) and one homo-zygous recessive individual; while the expected phenotypic ratio is 3:1 (i.e., 3 dominant expressing: 1 recessive expressing).
Which step occurs in meiosis to prepare for fertilization in sexually
reproducing organisms?
Answer: 12 sexual reproduction and meiosis concept outline
Explanation: The process of meiosis produces unique reproductive cells called gametes, which have half the number of chromosomes as the parent cell. Fertilization, the fusion of haploid gametes from two individuals, restores the diploid condition. Thus, sexually-reproducing organisms alternate between haploid and diploid stages.

The genetic researchers at Bay Medical Company are interested in spiders with the trait for medium silk flexibility. They
think this sik can be used for medical purposes such as for making stitches and for creating artificial tendons. Why do
you think offspring B has the medium silk flexibility trait?
Answer:
Due to similar shape.
Explanation:
I think offspring B has the medium silk flexibility trait because this offspring B is identical to the spider that is responsible for medium silk flexibility trait. There are some offspring identical to male parent spider due to the presence of dominant allele whereas very littles number of offspring is similar in appearance with the female spider due to recessive allele. If the male spider has medium silk flexibility trait so more number of offspring has medium silk flexibility trait as compared to others.
The people at the Medical research bay company are researching on spiders. the trait for the medium silk flexibility. The silk can be used for medical purposes and creating other tendons.

Examine the photographs of 16 species of anole lizards and sort them into as many groups as you want according to how they appear in the photographs. Explain how you grouped the lizards and your rationale for the various groupings. If you picked a body feature, speculate about the advantages or disadvantages of such a body feature in the environment that species occupies.
Answer:
On the basis of physical appearance.
Explanation:
We grouped the lizards into various groups on the basis of similarities and differences in the body structure, appearance and colour etc. The legs of anole lizards are small legs with pads on their feet for gripping surfaces which give them the advantage to climb up the trees while on the other hand, these small legs can't help in the survival on the land because they can't run too fast from their predators with these short legs so these legs has benefit in climbing the tree but disadvantage in running on the land.
