The gravitational force that pulls objects toward Earth is greater than the force that pulls objects toward the moon. Which property of matter is affected by this difference in gravitational force?
Answer:
Gravity
Explanation:
why is left lung smaller than right lung
Answer:
I guess I should guess sit correct.
Explanation:
if the left lung's size is equal to the right lung's size, then there wont be any space for the heart.
so the space left on your left lung is occupied by the heart.

Consider, pea plants, for which green color is dominant to yellow color, and two leaves are dominant to three. A cross between two plants that are heterozygous green and heterozygous tall is completed. What is the phenotypic ratio?
9:3:3:1
1:1:1:1
1:3:3:9
9:1:3:3
Answer:1339
Explanation:
9:3:3:1 is the phenotypic ratio, a phenotypic ratio is a numerical comparison of two phenotypes that demonstrates how frequently the occurrence of one trait corresponds with another.
What is phenotypic ratio?The phenotypic ratio produced from a test cross is used by researchers to determine the gene expression for generations of an organism.
Researchers use the phenotypic ratio obtained from a test cross to determine gene expression for subsequent generations of an organism. A test cross is a genetics method for determining the genotypes and traits of an organism's offspring.
9/16 G-T- --> Green-colored and two-leaved plant
3/16 G-tt ----> Green-colores and three-leaved plant
3/16 ggT---> yellow color and two-leaved plant
1/16 ggtt ---> yellow color and three-leaved plant
Therefore, 9:3:3:1 is the phenotypic ratio, hence option A is correct.

In each case, what is the end product of burning the fossil fuel, and where does it go?
Answer:
when fossil fuels are burned they release carbon dioxide and other greenhouse gases which traps heat in the atmosphere and making them primary contributors to global warming and climate change
Explanation:
When fossil fuels are burnt, they generally give rise to six different kinds of products, these are carbon dioxide, sulfur dioxide, carbon monoxide, lead, nitrogen oxides, and particulate matter.
• Of these, the main product of the burning of fossil fuels is carbon dioxide.
• When the burning of fossil fuels takes place, the carbon dioxide and other greenhouse gases get released into the atmosphere in excess amounts and trap heat more than expected.
• Thus, making them the primary contributors to climate change and global warming.

Arnoldo is a botanist studying inheritance in flowers. When he crosses pure breeding red carnations with pure breeding white carnations, the offspring in the F1 generation have pink flowers. In the F2 generation, some
flowers are red, some flowers are white, and some flowers are pink When he crosses blue poppies with yellow poppies, all the offspring in the Fgeneration have both blue and yellow petals In the F2 generation, some
have only blue petals, some have only yellow petals and some have both yellow and blue petals
Which of the following correctly identifies the inheritance patterns Arnoldo is observing?
Flower color in the poppies is polygenic, while flower color in the carnations is controlled by multiple alleles
Answer:
A is the answer
Explanation:
The statement that correctly identifies the inheritance patterns is the yellow allele is incompletely dominant over the blue allele in the poppies, while the red and white alleles in the carnations are codominant. The correct option is D.
What is inheritance?Genetic information is transmitted from parent to kid through inheritance. Members of the same family typically share traits in common because of this.
As it relates to genetics, the term "inherited" describes a feature or variation that is encoded in DNA and passed from parent to child during reproduction. The laws of Mendelian genetics govern inheritance.
Therefore, the correct option is D. The yellow allele is incompletely dominant over the blue allele in the poppies, while the red and white alleles in the carnations are codominant.

A. Polypeptide
B. Polyamino
C. Polymer
D. Protein
Polyamino is not a name for a chain of amino acids.
what are amino acids?
An amino acid is a fundamental molecule that serves as the building block for proteins. There are 20 different amino acids. A protein consists of one or more chains of amino acids (called polypeptides) whose sequence is encoded in a gene. Some amino acids can be synthesized in the body, but others (essential amino acids) cannot and must be obtained from a person’s diet.
therefore option B is the correct answer.
