Answer:
Small and Family Farms. More than 90 percent of farms in the U.S. are classified as small, with a gross cash farm income of $250,000, or less. These farms, most of which are family-owned and operated, confront considerable challenges due to current trends, such as increased movement into cities, an aging population, farm consolidation, and changing weather patterns.

Why don't offspring always look like their parents?
A. The way offspring look also depends on their behavior traits.
B. The way offspring look also depends on the amount of nutrients received during birth.
C. The way offspring look depends on the combinations of alleles they inherit and on interactions between traits and the environment.
D. The way offspring look depends on the combinations of alleles they inherit and on interactions between genes and the environment.
Answer: The answer is C. The way offspring look depends on the combinations of alleles they inherit and on interactions between traits and the environment.
Explanation: Each baby isn't an exact clone of the parents. They share different alleles from different parents. Think about it. If the dad and mother didn't look alike then how could the baby have the same physical features as both combined. So basically, The way offspring look depends on the combinations of alleles they inherit from their parents.

Identify which type of natural selection is described in each case below.
Results in the evolution of the species:
Results in new species:
Favors traits at the two extremes:
No increase in diversity:
One extreme trait is favored:
Diversity decreases:
Diversity increases:
Answer:
Results in the evolution of the species: Directional selection
Results in new species: Disruptive selection
Favors traits at the two extremes: Disruptive selection
No increase in diversity: Directional selection
One extreme trait is favored: Directional selection
Diversity decreases: Stabilizing selection
Diversity increases: Disruptive selection
Explanation:
Directional selection which is also known as positive selection is known to be a mode of natural selection. In this type of selection, an extreme phenotype is favored over other phenotypes. This makes the allele frequency to move in the direction of that phenotype and this takes place over time.
Disruptive selection (known to be diversifying selection) talks about the certain changes in the population genetics whereby extreme values of a particular trait are favored over intermediate values. This results in new species.
While Stabilizing selection is a natural selection whereby there is a stabilization of the population mean on the particular value of a non-extreme trait. Here the diversity is decreases.
Answer: A) directional selection
B) disruptive selection
B) disruptive selection
A) directional selection
A) directional selection
C) stabilizing selection
B) disruptive selection

A forest fire took over this forest ecosystem, burning a majority of the trees in the area. How would this forest fire impact different two different consumer populations in this ecosystem?
Answer:
Herbivore and carnivores.
Explanation:
This forest fire greatly affected two consumer populations such as herbivores and carnivores because herbivores has no food available due to forest fire. The unavailability of food for the herbivores leads to the decrease in herbivore population that also adversely affected the population of carnivore ( those organisms that feed on herbivores) so both are affected from the forest fire.
Explain how too much carbon dioxide in the atmosphere causes these changes.
Answer: Carbon dioxide becomes a poisonous gas when there is too much of it in the air you breathe. Besides the effects it can have on the planet and the atmosphere, carbon dioxide poisoning can lead to central nervous system damage and respiratory deterioration in humans and other breathing creatures.

4. What role do carrier proteins play in facilitated
diffusion?
Answer:
Carrier proteins can change their shape to move a target molecule from one side of the membrane to the other. ... The carrier proteins involved in facilitated diffusion simply provide hydrophilic molecules with a way to move down an existing concentration gradient (rather than acting as pumps).

What’s the different properties of hbA and HbS
Answer:
The isoelectric point of normal HbA is 6.9 [91], but HbS has two fewer negative charges per hemoglobin molecule than HbA because glutamic acid residues in the β-chains of HbS were substituted by the valine residues [5], [6]. It shows that HbS has more hydrophobicity than HbA in this condition [10]

What are two ways to identify NESW?
Answer:
-The sun
-shadow
Explanation:
-The sun rises in the general direction of east and sets in the general direction of west every day, so you can use the location of sunrise or sunset to get an approximate idea of direction.
-The shadow will always move - or, more precisely 'grow' in the west-to-east direction. (Before noon, when the sun is rising, the shadow will grow shorter and after noon when the sun is setting, the shadow will grow longer)

(_______) stars, however, will last for several billion years, because
they burn their fuel much more slowly. *
Answer:
Smaller
Explanation:
Life Cycle of a Star
Stars are formed in clouds of gas and dust, known as nebulae. Nuclear reactions at the centre (or core) of stars provides enough energy to make them shine brightly for many years. The exact lifetime of a star depends very much on its size. Very large, massive stars burn their fuel much faster than smaller stars and may only last a few hundred thousand years. Smaller stars, however, will last for several billion years, because they burn their fuel much more slowly.

No other kind of atom can form the number and variety of molecules that can because it can bond to 4 other atoms at the same time to make carbohydrates, lipids, nucleic acids and proteins.
Hydrogen
Oxygen
Carbon
Sodium
Answer: carbon
Explanation:
Carbon is the common “ building block” because of its ability to to bond to 4 different elements at the same time.
The atom that can form a number and variety of molecules because it can bond to 4 other atoms at the same time to make carbohydrates, lipids, nucleic acids and proteins is called carbon.
Carbon atom is the central element that contributes to the formation of biological macro molecules.
Examples of these biological macro molecules that are essential for life are carbohydrates, lipids, nucleic acids and proteins.
Carbon atom is considered a very important atom that can form the number and variety of biological molecules because:
each carbon atom can form four chemical bonds with other atoms,this is because it has sp³, sp², or sp hybridization in its compounds.it forms bond in all these dimensions and make molecules with complicated shapes.Learn more here:

c. dehydration synthesis.
Explanation:
The monomer is a molecule that reacts with one or more monomer molecules to form a chain or polymer. In the given reaction the two amino acids react together to form a dipeptide.
The dimer is a molecule that is made up of two monomers and in this reaction, two amino acids form a dimer dipeptide. The dehydration synthesis is a reaction in which a water molecule is lost.
