Answer:

Ribosomes are the sites in a cell in which protein synthesis takes place. ... Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes called a ribozyme or catalytic RNA to reflect this function.

Explanation:

Answer:A meteoroid is a chunk of space rock. If it burns up while entering the Earth’s atmosphere it’s called a meteor and if a piece lands, it’s called a meteorite.

Millions of meteoroids travel through the Earth’s atmosphere every day, but most are small and burned up quickly. Very few reach the ground.

When a meteoroid hits the atmosphere of the Earth, they can be travelling as fast as 130,000 mph (209,215 km).

The blast caused by the shockwaves of the Chelyabinsk meteor in Russia was picked up by infrasound sensors on the other side of the world. Below is a video of that meteor.

The buying and selling of meteorite pieces in South Africa is illegal.

A meteorite that is seen or detected as it lands are called “falls”, with those that are discovered later being referred to as “finds”.

Meteoroids more than 10 metres in diameter are classified as asteroids.

Of the 500 estimated meteorites that reach the ground every year, only five or six are recovered for scientists to study.

Answer:

2 is the right answer

Explanation:

they do not produce fruit or flowers  think of a pine treee of a spruce tree

Gymnosperms are a group of seed plants that produce no flowers or fruit. Therefore, option B is correct.

A relatively tiny class of plants known as gymnosperms produce seeds and lack flowers. This means that unlike in a fruit, where the seeds are formed inside the reproductive structure, they are produced on the surface of the reproductive structure.

The Coniferophyta, Cycadophyta, Gingkophyta, and Gnetophyta are the four primary phyla that makeup gymnosperms. Conifers, which have needle-like leaves and thrive in arid, cold climates, are the most common gymnosperm.

Some examples of gymnosperms are ginkgo, pine, melinjo. sago palm, cedars, and spruces. Gymnosperms are a group of seed plants that produce no flowers or fruit. Therefore, option B is correct.

Answer:

The correct answer would be - zero miles, 600 miles.

Explanation:

She started from the same point and after the trip, she ended it on the same point in Philadelphia therefore the displacement is expected to be zero.

The distance she traveled would be 2 into 300 miles as she traveled to her sister and traveled back from there so

Distance = 2*300

= 600 miles.

Thus, the correct answer would be - 0 and 600 miles.

The first part of finding out Lucy having ADA-SCID was when I realized there were no HIV proteins in her blood, getting rid of the possibility of her having HIV. Then, I realized she had a high number of Deoxyadenosine in her blood. This proves she has ADA-SCID because when the ADA doesn't work you find excess amounts of Deoxyadenosine in the blood.

B. All organisms that cannot synthesize their food by means of photosynthesis or chemosynthesis are heterotrophic.

Explanation:

There are three ways for a plant to obtain their food, photosynthesis, chemosynthesis, and heterotrophic. Photosynthesis is when the plant makes it's own food. If it can not get it's food from chemosynthesis or photosynthesis, it has to be an heterotrophic plant. The answer to the question is B. All organisms that cannot synthesize their food by means of photosynthesis or chemosynthesis are heterotrophic.

Answer:

Due to difference in the methods that is used for analysis.

Explanation:

The two methods give different results because we used two different types of measurements i. e. metric measurement and nonmetric traits. In the metric measurement, we calculate the quantitative character of an individual that gives information about the current status of an individual, while on the other hand, in non-metric traits refers to the method which is used to evaluate genetic connections within and between populations that were present in the past.

Answer:

Soap has chemicals that kill bacteria

When you wash your hands with soap and water, you surround any microorganisms on your skin with soap molecules. The hydrophobic tails of the free-floating soap molecules attempt to evade water; in the process, they wedge themselves into the lipid envelopes of certain microbes and viruses, prying them apart.

Camels ears are lined with fur to keep out sand and other blowing matter

The Cambridge family includes the unusually shaped Arabian camel (Camelus dromedarius), also referred to as the one-humped camel. This animal is perfectly suited to the harsh desert climate and high levels of heat stress. Thus, option B is correct.

Camels have evolved to survive in extremely hot and cold climates.In contrast to many other mammals, camels store the majority of their body fat in their humps, which allows for better thermoregulation. It makes it easier for them to release heat from their body in hotter climates. Camels rarely perspire.

Camels are ideally suited for desert survival. They have developed wide, flat feet to disperse their weight across the sand, among other adaptations. Thin fur everywhere to allow for rapid heat loss, and dense fur on the top of the body for shading.

Therefore, The kidney may be able to retain water if the generation of cholesterol is reduced. Camels produce pee that is highly concentrated, retaining the maximum amount of water.

The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA.

Answer:

S phase, S phase is the period during which DNA replication occurs.

Answer:

From the given observations we can say that there are 2 genes that are responsible for normal learning. It is also given that the dunce and rutabaga mutations are the mutations of 2 different genes.

Due to complementation which is a phenomenon of restoration of normal phenotype if mutants are crossed, it is found that the flies have normal learning behavior if both mutants are crossed.

Let's assume that the Drosophila having this learning effect and it is due to genes D and R where D is the normal gene and dd is the case of mutation that results in duncy phenotype. Similarly, Gene R is responsible for normal learning, and rr results in rutabaga phenotype.

Cross between ddRR (duncy) x DDrr (rutabaga)

Gametes - dR x Dr

F1 progeny - DdRr    

Thus, in heterozygous cases, a single copy of both wild-type alleles D and R complement each other.

Answer:

a. can cause large changes in enzymatic activity.

Explanation:

An enzyme refers to a biological catalyst that is typically used to speed up (accelerate) the rate of a chemical reaction by lowering the activation energy of its reactants.

When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy. Also, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates. An increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.

An allosteric effector can be defined as an agent, organ or molecule that is being binded to an enzyme at a site, thereby causing a reduction (negative effect) or an increase (positive effect) in an enzyme activity.

Hence, an allosteric effector can cause large changes in enzymatic activity because it acts as an intermediary and mediates specific effect in a metabolic pathway.
