Answer:
Although no one knows when the first outer crust of the planet formed, some scientists believe that the existence of a few grains of zircon dated to about 4.4 billion years ago confirm the presence of stable continents, liquid water, and surface temperatures that were probably less than 100 °C (212 °F).

Answer:
Explanation:
Sunflowers thrive in slightly acidic to somewhat alkaline soil (pH 6.0 to 7.5). Sunflowers are heavy feeders, so the soil needs to be nutrient-rich with organic matter or composted (aged) manure. Or, work in a slow release granular fertilizer 8 inches deep into your soil.The stem of the sunflower has bristles, these are to prevent water loss as well as deter animal predation. The leaves are oppositely positioned leaves
It has adapted to this necessity by having a heliotropic head which rotates to follow the sun, hence the name sunflower. ...

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.
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).

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.

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.

Which is NOT
involved with an
inflammatory
response?
A. fever - increased temperature
B. slowed blood flow
C. white blood cells move to the area of infection
D. inflammation in area
Out of the given answers B. slowed blood flow is not involved with an inflammatory response.
During an inflammatory response, several physiological changes occur in the body to combat infection or injury. Let's briefly discuss the other options to understand their involvement in the inflammatory response:
A. Fever - increased temperature: Fever is a common feature of an inflammatory response. It is caused by the release of certain chemicals called pyrogens that act on the hypothalamus in the brain, raising the body's temperature. The increased temperature helps to enhance the immune response and inhibit the growth of certain pathogens.
C. White blood cells move to the area of infection: Inflammation triggers the recruitment of white blood cells, such as neutrophils and macrophages, to the site of infection or injury. These immune cells play a crucial role in identifying and eliminating pathogens, as well as removing damaged tissue and promoting tissue repair.
D. Inflammation in the area: Inflammation is a hallmark of the inflammatory response. It involves localized redness, swelling, heat, and pain at the site of infection or injury. Inflammation helps to isolate the area, prevent the spread of infection, and promote healing.
B. Slowed blood flow: Slowed blood flow is not a characteristic of the inflammatory response. On the contrary, inflammation often leads to increased blood flow in the affected area, resulting in redness and heat. The increased blood flow facilitates the delivery of immune cells, oxygen, and nutrients to the site, aiding in the immune response and tissue repair.
In conclusion, slowed blood flow is not involved in the inflammatory response, while the other options (fever, white blood cell recruitment, and inflammation) are key components of the inflammatory process. Therefore, the correct answer is B.
