helllllppppppppppppp I WILL GIVE BRAINLIEST
Explanation:
The bloodstream carries the glucose-a type of sugar produced from the digestion of carbohydrates and other foods-to provide energy to cells throughout the body. Unused glucose is stored mainly in the liver as glycogen.
Insulin, glucagon, and other hormone levels rise and fall to keep blood sugar in a normal range. Too little or too much of these hormones can cause blood sugar levels to fall too low (hypoglycemia) or rise too high (hyperglycemia).
Normally, blood glucose levels increase after you eat a meal. When blood sugar rises, cells in the pancreas release insulin, causing the body to absorb glucose from the blood and lowering the blood sugar level to normal. When blood sugar drops too low, the level of insulin declines and other cells in the pancreas release glucagon, which causes the liver to turn stored glycogen back into glucose and release it into the blood. This brings blood sugar levels to back up to normal.
Which of these are cellular activities that sustain a single-celled organism through its lifetime? Select all that apply. The transmission of DNA to offspring, Processes by which individuals produce offspring, Development into a multi-celled adult, Increases in cell size and volume
Explanation:
The transmission of DNA to offspring.
Processes by which individuals produce offspring.
Increases in cell size and volume
A single-celled or 'unicellular' microorganism is a microscopic organism composed of only one cell. Unicellular microorganisms asexually reproduce to produce offspring.
The cellular activities that sustain a single-celled organism through its lifetime include:The transmission of DNA to offspringProcesses by which individuals produce offspringIncreases in cell size and volumeUnicellular microorganisms include, among others, prokaryotic bacteria, unicellular fungi (e.g., yeast), and unicellular protists (e.g., Amoeba).Reproduction refers to the process by which organisms transmit their genetic material (DNA) to offspring.In unicellular organisms, the process of reproduction is asexual (without the involvement of gamete formation).During their lifetime, unicellular organisms increase in size and volume to carry out their metabolic functions.In conclusion, unicellular organisms share different cellular activities which include the transmission of DNA to offspring, processes by which individuals produce offspring and increase in cell size and volume.Learn more in:

Which point is on the interior of ZBAC?
D

O point D
Opoint A

A
Opoint C
point B
Answer:
Point D.
Explanation:
A shape's internal angle is referred to as an interior angle. An external angle is any angle that is outside of a form.
What is Interior angle?One of the shape's lines is extended past the intersection point to create an external angle. Two angles combine to form a straight line.
This is significant because it indicates that, given the measurement of the other angle, we can always obtain the measure of the missing angle because we know that a straight line measures 180.
For instance, the rhombus below only provides us with an outside angle measurement. An interior angle is any angle that is located within of a form. An external angle is any angle that is outside of a form. One of the shape's lines is extended past the intersection point to create an external angle.
Therefore, A shape's internal angle is referred to as an interior angle. An external angle is any angle that is outside of a form.

5-7 sentences that describe the life cycle of a star
Answer:
The accurate existence of a star depends extremely on its size.
Explanation:
The mass decides the life cycle of a star whereas the central sequence star shines, hydrogen in its core is turned into helium by nuclear fusion. Meanwhile, the hydrogen supply in the core begins to run out, and the star is no longer producing heat by nuclear fusion, the core enhances unstable and contracts.The stars are grown in clouds of vapor and dust which are identified as Nebulae. The nuclear reactions toward the center of stars produce sufficient energy to get them to shine brightly for several years. Sun is the nearest star to the earth. Numerous stars are visible to the bared eye from Earth through the night, resembling twinkling dots due to their enormous distance from the Earth.Learn more about life cycle of star, refer:

Air pollution and climate change
Problems
Carbon overload in the atmosphere and seawater. The CO2 in the atmosphere absorbs and re-emits infrared wavelength radiation. Which causes the air, soil, and ocean surface water to warm. Which is a good thing without this, the earth would freeze. Unfortunately, there is too much carbon in the air now.
The burning of fossil fuels, agricultural deforestation, and industrial activities have increased the concentration of carbon dioxide in the atmosphere from 280 parts per million (ppm) 200 years ago to about 400 pm today. Whether it is scale or speed, this is unprecedented growth. The result: a change in the climate.
Carbon overload is just one form of air pollution caused by burning coal, oil, natural gas, and wood. The World Health Organization recently estimate that one in nine deaths in 2012 were caused by diseases caused by carcinogens and other poisons in the polluted air.
Solution:
Replace fossil fuels with renewable energy. Forest restoration. Reduce agricultural emissions. Changing industrial processes, The good news is that clean energy is abundant, but it needs to be harvest.
Many people say that it is feasible to use existing technologies to achieve a 100% renewable energy future, but the bad news is that even though renewable energy infrastructure (solar panels, wind turbines, energy storage, and power distribution systems) are widely available and Become cheaper and more efficient.
Experts have always said that our applications are not fast enough to avoid catastrophic climate damage.
Deforestation
Problem
Species-rich wild forests are destroye, especially in tropical areas. Usually to make way for cattle farms, soybean or palm oil plantations, or other monocultures. Today, about 30% of the earth’s land area covers by forests.
This is about half of what it was before agriculture started about 11,000 years ago. Approximately 7.3 million hectares (18 million acres) of forest are destroyed every year, mainly in the tropics. Therefore Tropical forests used to account for about 15% of the earth’s land surface; now they have fallen to 6% or 7%.
Solution
Most of the remainder has degraded by logging or burning. Natural forests are not only a reservoir of biodiversity but also a carbon sink. Excluding carbon from the atmosphere and ocean.
Therefore Restore degraded areas by replanting native tree species. This requires strong governance. But many tropical countries are still developing, their populations are growing. So that The rule of law is unbalanced, and cronyism and bribery are common in allocating land use.

In response to injury, cell fragments called platelets get activated to induce clotting. Activated platelets release factors that can in turn bind to specific membrane receptors on nearby cells. What type of signaling would this be considered
Answer:
Activated platelets express negative phospholipids on the exterior leaflet of their cell membrane, release vasoactive compounds, release cytokines, and release growth factors.
When an injury causes a blood vessel wall to break, platelets are activated. They change shape from round to spiny, stick to the broken vessel wall and each other, and begin to plug the break. They also interact with other blood proteins to form fibrin.
Platelets contribute their hemostatic capacity via adhesion, activation and aggregation, which are triggered upon tissue injury.
Explanation:
How does deforestation contribute to climate change?
