Answer:
An ecologist must consider both of the speciation and extinction of an organism or when analyzing the diversity the life on earth because of the following reasons;
- It is a role of an ecologist
- It is part of their job
- This will tell the existence of the organism
- The organism’s life span on earth
- How it was existed and were extinct
Explanation:
Answer:
They showed how organic molecules could be made from Earth's early atmosphere.
Explanation:
Miller-Urey experiments were based on the ides of a-bio-genesis. It means the production of life through the non biological factors. In this experiment it shows that life can be produced through chemicals and molecules that were found in the early form of earth and is composition.
It kind of gives off to the evolution theory and the amino acids which are the building blocks of life and were given rise to during the simulation.
When a cell divides, each daughter cell must receive its full complement of genetic material in the form of chromosomes containing DNA, or deoxyribonucleic acid. A chromosome is made up of two long strands of DNA and several types of proteins . A DNA strand is composed of a long backbone of sugar and phosphate units . One of our different nucleotide bases -- A, T, C or G -- hang off each sugar unit. The sequence of the bases encodes genetic information. The three steps in the process of DNA replication are initiation, elongation and termination
If you mean where lipids come from, we get them from food like butter, oils, avocados, etc.
If you're asking how we absorb lipids, lipids get broken down into fatty acids and glycerol which are absorbed by the lymphatic system through lacteals in the villi of the small intestine.
Answer:
Probability that both cats described will have an offspring who is heterozygous for both traits is 50%, according to the scenario given.
Explanation:
When a cat amazing and bashful is crossed with a cat average and boring, it is a crossing where two traits are taken into account that will be segregated independently by the parents, and the result can be obtained by analyzing their genotypes and making the corresponding crossing in a Punnett square.
<u>Genotypes</u>:
- <u>Male cat</u> AABb
- <u>Female cat
</u> aabb
<u>Crossing</u>
:
Punnett's square (simplified)
<em>Alelles AB Ab</em>
<em>ab AaBb Aabb</em>
<em>ab AaBb Aabb</em>
<u>Offspring</u>:
- <em>AaBb amazing and bashful (heterozygous for two traits) 50%</em>
- <em>Aabb amazing and boring (heterozygous for trait A ans homozygous recessive for B) 50%</em>
<u><em>Probability that they will have an offspring who is heterozygous for both traits is 50%.</em></u>
