Answer:
A hypothesis that is not possible, or has less strength, to explain how life arose on Earth is that it originated from cells that were delivered by meteorites from outer space (option D).
Explanation:
Although it is a hypothesis that has scientific foundations to be considered, the origin of life coming from organic molecules or cells from space -called Panspermia- has not been completely proven because:
- It provides information on the origin of cells or organic matter, but it doesn't specify how life was formed from them.
- It does not resolve the question of how a cell could withstand a journey through space or endure the high temperatures when a meteorite entered the primitive atmosphere.
These arguments make the hypothesis of the arrival of the first cells from outer space the least accepted today.

Answer:
1. Tertiary Care
Explanation:
Tertiary care is a specialized health care for inpatients over an extended period of time usually on referral by primary or secondary health care personnel, involving contemporary and complex procedures and treatments.
Examples include: Cancer management, complex medical and surgical procedures.
Subacute Care is defined as an inpatient care for someone who has an acute illness. It is treatment administered immediately after acute hospitalization or in some cases, in place of it to treat and provide care for people with medically complex conditions.
Answer:
A gene transmitted to males from the maternal line and from fathers to daughters.
Explanation:
Gregor Mendel through his research on pea plants, came up with three laws which are:
- <em> The Law of Segregation of genes: Each inherited trait is defined by a pair of gene alleles. Genes are randomly separated to the sex cells so that sex cells contain only one allele of the pair. </em>
- <em>The Law of Dominance: An organism with alternate forms of a gene will express the form that is dominant.
</em>
- <em>The Law of Independent Assortment: Genes for different traits are sorted separately from one another so that the inheritance of one trait is not dependent on the inheritance of another.
</em>
<em></em>
In His work, he established the basic patterns of inheritance and it wasn't until after his death that sex linked inheritance patterns were identified.
He believed that a pair of genes called alleles, were transmitted, each allele from one parent and both alleles transmitted from each parent constituted the complete pair in the offspring.
However, if different variants of the same gene were inherited from both parents, the dominant gene is expressed in the offspring (phenotype).
Since the basis of his work established genes being equally transmitted by both parents to offspring, the variations being due to dominance, genes transmitted from mother to son and from father to daughter, follows the Mendelian pattern of inheritance.
Well, since im living my first one still.. Ill do whatever i want in the first one, and then live out the second one as a good Christian to the best of my ability
hope this helps
Answer:
Since all cells in our body contain DNA, there are lots of places for mutation to occur; however, some mutations cannot be passed on to the offspring and do not matter for evolution.
