Answer:

Carbohydrates

Explanation:

Carbohydrate is a macronutrient formed primarily of carbon, hydrogen and oxygen molecules. This macronutrient when ingested and absorbed is responsible for releasing glucose, providing energy to cells as the primary source of cellular energy, and maintaining glycemic metabolic maintenance for the body to continue to function well. Carbohydrates are the most abundant biomolecule present in the body and play a key role in many parts of our body.

Carbohydrates are involved in energy storage and transport, immune system, reproductive system, fertilization, blood clotting, among other processes that are vital in the body.

The sun is the primary source
Sedaia [141]

The Sun is the primary source of energy for Earth's climate system is the first of seven Essential Principles of Climate Sciences.

Principle 1 sets the stage for understanding Earth's climate system and energy balances.

The Sun warms the planet, drives the hydrologic cycle, and makes life on Earth possible.

Joe, a hiker, stands at the top of a hill on a trail above the ocean. Joe's friend Dave is just starting out at the trailhead, w
Rashid [163]

Answer: 1, 2, 4 are accurate.

Explanation:

1. Joe is on a hill (on a trail) above the ocean. The beach and ocean are at similar altitudes. Therefore Joe is at a higher altitude than if he was at the beach.

2. Since Joe is on a hill, he has a higher altitude than at sea level. Air at a higher altitude has lower density because there is less air "ontop" of itself than at lower altitudes. As well, his hill is above the ocean, which means there is a lot of water, making the air more humid than where he is. Humidity also makes air denser.

4.The air pressure will decrease if Joe goes up to higher altitudes because there will be less air on top of itself.

Which human action has not lead to significant changes in Earth’s biomes?
valina [46]
The burial practices of humans have not led to any significant changes in Earth's biome. Matter can not be created nor destroyed. Burial practices lead to burying the dead bodies into the Earth, where they are decayed by the action of several microbes and insects. The organic and inorganic compounds are added to the Earth.

Attached earlobes are recessive to free earlobes. What genotypic ratio is expected when an individual with attached earlobes mat
Marianna [84]

Answer:

C

Explanation:

This is a monohybrid cross between involving a gene coding for earlobe. The allele for free earlobe (F) is dominant over that of attached earlobe (f).

N.B: let F represent the gene involved.

A genotypic ratio is the ratio derived from the offsprings based on the actual genetic make-up and not based on their phenotypic appearance as in phenotypic ratio.

A homozygous individual is an individual having the same kind of alleles for a gene while a heterozygous individual is one that has two different alleles i.e. combination of the dominant and recessive allele.

The monohybrid cross is between an individual with attached earlobe (ff) i.e. homozygous recessive individual. (Note that, a recessive trait will only be expressed in a homozygous state) and a heterozygous free earlobeb individual (Ff). (See attached picture). Ff × ff

The resulting four offsprings will

be expected to have only two distinct genotypes i.e heterozygous (Ff) and homozygous recessive (ff) in an equal ratio i.e. 2:2 ~ 1:1
