Answer:
True
Explanation:
the Earth and the Moon are kept in orbit by gravity and mass.
Answer:
D. is responsible for most of the skin's structural strength.
Explanation:
A. contains no blood vessels.
False. The dermis contains blood vessels together embedded in it along with the sweat and sebaceous or oil glands, hair follicles, and nerve endings.
B. functions as a padding and insulation.
False. The fat layer that is located below the dermis is the one responsible for padding and insulation.
C. is divided into three distinct layers
False. The dermis is divided into only two separate layers. These are the papillary layer or the upper layer and the reticular layer or the lower layer.
D. is responsible for most of the skin's structural strength.
Yes, the dermis functions for providing the skin's structural strength because of it's thick fibrous and elastic tissue layer. This layer consists primarily of collagen and elastin that also allows for the skin's flexibility.
E. is made of epithelial tissue.
False. The dermis is made up of fibrous and elastic tissue. It is the epidermis which is composed of the epithelial tissue.
Answer: consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder).
Each parent contributes one allele describes the influence that parents have on whether or not offspring inherit a genetically inherited trait.
Explanation:
Allele is a form of gene present on the chromosome. Human have 2 alleles for a trait on a chromosome. Each parent contributes one of its allele to the progeny.The alleles for the gene are present on the same locus of chromosomes.
The alleles are either dominant or recessive. The contribution of alleles and the expression of trait decide the alleles of offspring.
The phenotype is determined by the allele expressed as short or tall and human ABO blood type.
An allele is sequence of DNA. The organism having two same alleles are homozygous and having two different alleles are heterozygous.
