Answer:

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

Answer: mutations that natural selection can work on. 4.) How do scientists calibrate a molecular clock? ... they compare the number of positive mutations that have occurred in a particular species with the number of negative mutations that have occurred

Explanation:

Answer:

B, because the relationship between an mRNA codon and its corresponding amino acid is called the genetic code. The three-nucleotide code means that there is a total of 64 possible combinations (4 3, with four different nucleotides possible at each of the three different positions within the codon)

Answer:

i think it is others rock because mineral are inorganic matter

Explanation:

Mineral nutrients are usually obtained from the soil through plant roots, but many factors can affect the efficiency of nutrient acquisition. First, the chemistry and composition of certain soils can make it harder for plants to absorb nutrients.

Answer:

1. GCA:arginine

2. AGU:cysteine

3.UAC:Tyrosine

4.AUG:Methionine

The correct amino acids which are encoded by the codons are GCA- Alanine, AGU- Serine, UAC- Tyrosine, and AUG- Methionine.

A codon is a specific three nucleotide sequence of nucleotides such as DNA or RNA which are transcribed on an mRNA that corresponds to a specific amino acid or a stop signal during the process of protein translation in the ribosome of cytoplasm.

In the eukaryotic cells, there are 64 codons of four nucleotide are observed, from which 61 codons codes for twenty amino acids whereas three codes for stop codons or termination codons.

The amino acids which are encoded by the following codons include: GCA- Alanine, AGU- Serine, UAC- Tyrosine, AUG- Methionine. AUG also acts as the initiation codon i.e., it is responsible for the initiation of translation in the eukaryotic cell.

Answer:

an environmental change that causes the larger but unadaptable species to die off

Explanation:

Two populations live in the same habitat and compete for food. The first group has larger and multiplies through asexual reproduction the second reproduces sexually an environmental change that causes the larger but unadaptable species to die off.

If there has no process of meiosis takes place chromosome number will be doubled disturbing the genetic make up of the organism. If no meiosis has been takes place then the resulting of the zygote will be of double the number of the chromosomes. The genetic makeup would change entirely. The process of the meiosis halves the number of chromosomes in haploid cell and maintain the serenity of organism.

The process of the meiosis due to crossing over, genetic variation occurs which let the offspring receive favourable alleles to survive in new conditions and in the diploid organisms first the gametes are formed, then fertilization occurs and the diploid cell has  formed which gives rise to the organism having diploid cells.

Therefore, Two populations live in the same habitat and compete for food. The first group has larger and multiplies through asexual reproduction the second reproduces sexually an environmental change that causes the larger but unadaptable species to die off.

Answer:

Preparing at moderate height may improve ocean level execution in perseverance competitors. This was noted after the 1968 Olympics in Mexico City (7600 feet) when a few competitors found an improvement in their presentation after re-visitation of ocean level. Be that as it may, different competitors didn't see any distinction in execution. Studies have indicated improved high-impact power in sprinters who prepared at 6,000 feet for 10 days at that point performed at low elevation. Lower oxygen levels at elevation invigorate EPO prompting expanded red platelets or hematocrit. This viably permits more oxygen to be conveyed to the tissues. Basically, this is blood doping the regular way.  

Late examinations do propose profits by 'preparing low' and 'dozing high'. This incorporates hypoxic tents that numerous competitors are presently utilizing. These tents have a generator that extricates oxygen from the air, establishing a moderate height climate. Competitors at that point rest/relax in them for a few hours per day. This invigorates erythropoietin, subsequently expanding the hematocrit (red platelet tally). Without a doubt the 'live high, train low' idea may permit the best blend. One examination separated 39 contenders into three preparing gatherings; living and preparing adrift level, living at height and preparing adrift level, living at elevation and preparing at height. The two gatherings who inhabited height had expanded red platelets and VO2max, however just the gathering who lived high and prepared adrift level had improved race times. One clarification for this is that the live high, train low gathering can prepare more diligently and better use their blood's oxygen conveying limit. As a result of expanded red cell creation, all competitors preparing as well as resting at elevation should ensure they have proper iron stores and nourishment. This is particularly valid for ladies, as they will in general have lower iron stores because of occasional loss of blood through monthly cycle.

Answer:

The atmosphere absorbs the sun's energy and holds it as heat to warm the Earth

Explanation:

This is because the atmosphere also interacts sun radiations that comes in contact with through a process called molecular scattering. Light rays are very minute and there are alot of small molecules that float in the atmosphere and when light comes from the sun, the smaller molecules scatter the Ray's and it warm the Earth. Huge numbers of small molecules float in the atmosphere. There is a layer called ozone which absorb sun radiations.
