An island experiences a decade long drought which causes a die off of several plant species. The only plants that survive have extremely small seeds with less nutritional value. Parrots which live on the island and eat seeds are more likely to survive and successfully reproduce if they are smaller since smaller body size requires less calories. Over the course of the decade, the average body size of the parrot population decreases. Which of the following statements below are correct?
a. The parrot population has evolved.
b. This is an example of genetic drift.
c. This is an example of directional selection.
d. This population meets the conditions for the Hardy Weinberg equilibrium.
e. This is an example of stabilizing selection.
f. This is an example of natural selection.

The term ____ refers to anatomical structures that are found on the same side of the body.
A. Contramedial
B. Bilateral
C. Contralateral
D. Ipsilateral
Answer:
D. Ipsilateral
Explanation:
Ipsilateral is the occurrence of anatomical structures like the muscles, body organs, parts, etc., on the same side of the body. Thus, option D best fits the blank.
What is Ipsilateral?Ipsilateral is an anatomical terminology that defines the position, regions, and body structures that lie or occur on the same side of the body. On contrary, contralateral defines the structures on the opposite side of the body.
Bilateral is an anatomical term that refers to the anatomical structures that are present on the left and right side of the body and affects both sides. It defines the symmetry of the body.
Therefore, the Ipsilateral refers to structures of the same side.

Hey, I need help with these questions please:
Answer:
its B synthesis
Explanation:
Unlike true organisms, viruses cannot synthesize proteins, because they lack ribosomes (cell organelles) for the translation of viral messenger RNA (mRNA; a complementary copy of the nucleic acid of the nucleus that associates with ribosomes and directs protein synthesis) into proteins.

What effect would uncontrolled population growth have on land?*
A) increased soil fertility and decreased erosion
B) increased soil fertility and increased erosion
C) decreased soil fertility and decreased erosion
D) decreased soil fertility and increased erosion
(D) is the right answer ........
Uncontrolled population growth affect the soil fertility and soil erosion i.e. it decreases soil fertility and increases soil erosion.
what is uncontrolled population growth?uncontrolled population growth is the area where the proportion of urban population has increased faster than the nation's average rate of population growth.
what is soil erosion ?soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate.
what is soil fertility ?soil fertility is the ability of a soil to sustain plant growth by providing essential plant nutrients and favorable chemical, physical, and biological characteristics as a habitat for plant growth.
The population increases so that the demand for food increases, lack of arable land leads to intensive cultivation, reclamation to expand cultivation land on sloping hills increases soil erosion, causes degradation, infertile soil.
Therefore, use of chemical fertilizers and plant protection chemicals makes land resources, surface water sources of the mainland contaminated.
Reclamation makes area of forestland narrowed, depletion of natural resources, natural environment polluted.

Coronary heart disease is the main cause of death in our country. The following factors can increase the risk of an individual contracting this disease:
-smoking
-unbalanced diet
-unhealthy lifestyle
Explain how these factors can contribute to coronary heart disease.
Smoking :-
The coronary arteries inside us are responsible for supplying our heart muscles with O₂ rich blood. When people smoke, plaque builds up in the arteries & the O₂ rich blood will not get supplied to the hear muscles causing atherosclerosis / coronary heart disease.
Unbalanced Diet :-
Eating an unhealthy diet which is high in cholesterol & fats also causes atherosclerosis (coronary heart disease). Too much salt in the diet can also raise blood pressure which is another factor responsible for this disease.
Unhealthy Lifestyle :-
Unhealthy lifestyles like not exercising at all & being obese lead to atherosclerosis (coronary heart disease).

which type of organism can use photosynthesis to make food
Answer:Plants
Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis (Figure 1). Because they use light to manufacture their own food, they are called photoautotrophs (literally, “self-feeders using light”).
Explanation:
Answer:
All plants with green leaves, from the tiniest mosses to towering fir trees, synthesize, or create, their own food through photosynthesis. Algae, phytoplankton, and some bacteria also perform photosynthesis. Some rare autotrophs produce food through a process called chemosynthesis, rather than through photosynthesis.
During the process of photosynthesis,
which of the following is being created
by producers?
Answer:
Producers are the plants that use sunlight, water, and carbon dioxide to make their own food. They are called producers because they produce sugars from CO2 which they share with the rest of the world through photosynthesis. The carbohydrates, fats, proteins etc in your diet were all originally made by green plants! All green plants need is CO2 and water to live.
Explanation:
Answer:
Sugar and oxygen
Explanation:
energy from the sun converts the carbon dioxide and water it absorbs into sugar and the byproduct of oxygen
