Answer:
evidence of a gradual change of one species over time
Explanation:
Scientists can most likely expect to find evidence of the mass extinction of many species in the layers of rock that are about the same age as the impact. Therefore, option (A) is correct.
What is mass extinction?Mass extinction refers to a widespread and rapid decrease in the biodiversity on Earth, where a large number of species become extinct within a relatively short period of time.
The impact of a large meteor on the Earth can cause widespread destruction and have far-reaching consequences, including the extinction of many species. The impact can cause a global environmental crisis, which can include the release of massive amounts of dust and debris that block sunlight, leading to a drop in temperature and changes in climate.
These changes can have catastrophic effects on living organisms, particularly those that rely on photosynthesis for survival. As a result, scientists can expect to find evidence of the mass extinction of many species in the layers of rock that are about the same age as the impact.

Which types of plant cells must receive glucose from other plant cells? And how do you know?
Answer:
chloroplasts
Explanation:
cuz chlorophyll: green pigment found in chloroplasts that absorbs light energy required for photosynthesis.
It is essential for the mesophyll cells to receive a constant supply of glucose from the phloem in order to function properly.
What are mesophyll cells?
Mesophyll cells are a type of plant cell that are found in the mesophyll tissue of leaves. The mesophyll tissue is the layer of cells that is located between the upper and lower epidermis (surface layers) of the leaf, and it is responsible for photosynthesis, the process by which plants convert light energy into chemical energy.
Mesophyll cells are specialized for photosynthesis and energy production, and contain large numbers of chloroplasts, the organelles responsible for capturing light energy and converting it into chemical energy through the process of photosynthesis. The mesophyll cells also contain large numbers of mitochondria, the organelles responsible for producing ATP, the cell's main energy currency, through the process of cellular respiration. The mesophyll cells therefore play a vital role in providing energy for the plant, as well as for synthesizing other cellular products, such as hormones and enzymes.
Mesophyll cells are typically divided into two types: palisade mesophyll cells, which are elongated and located near the upper surface of the leaf, and spongy mesophyll cells, which are irregularly shaped and located near the lower surface of the leaf. The palisade mesophyll cells are responsible for absorbing light energy and conducting photosynthesis, while the spongy mesophyll cells provide a large surface area for gas exchange and help to regulate the temperature of the leaf.

How is the cycling of water driven by gravity and the sun
The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. ... Most precipitation falls back into the oceans or onto land, where, due to gravity, the precipitation flows over the ground as surface runoff.

ROCKER
173 terawatts
1.73 terawatts
17,300 terawatts
173,000 terawatts
D. 173,000 terawatts
Solar energy is radiant light and heat from the Sun that is harnessed using a range of technologies.The Earth receives ≈174 petawatts (PW) of incoming solar radiation (insolation) at the upper atmosphere Approximately 30% is reflected back to space while the rest is absorbed by clouds, oceans and land masses. The spectrum of solar light at the Earth's surface is mostly spread across the visible and near-infrared ranges with a small part in the near-ultraviolet.Since, 1PW=1000TW
Thus, 174 PW= 174*1000=174,000 TW.
Therefore, correct option is D.

how does water move through the water cycle
Answer:
The water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere, by the physical processes of evaporation, condensation, precipitation, infiltration, surface runoff, and subsurface flow. In doing so, the water goes through different forms: liquid, solid (ice) and vapor.

Answer:
Water will flow from microbe to the Jam.
Explanation:
Osmosis is defined as the movement of molecules from higher concentration to lower concentration of the solution across a semi-permeable membrane. In osmosis water moves from low concentration of solute to high concentration of solute.
In the given experiment, cell wall of bacteria acts as a semi-permeable membrane and sugar in jam and cytoplasm in bacteria act as solutes. Sugar in jam is strong solution means has high concentration of solute and cytoplasm in bacteria has low concentration of solute, which drives the movement of water from bacteria to the jam.
Hence, the correct answer is "Water will flow from microbe to the Jam."

PLEASE HELP!! Which of the following happens when cancer occurs?
1) the control of the cell cycle is impaired
2) cells cannot pass the G1 checkpoint
3) apoptosis or programmed cell death takes place
4) the cells can no longer enter the cell cycle
Explanation:
The answer is #1.
As cells become abnormal, old and damaged cells do not go through the cell cycle and can not regenerate like usual & the damaged. Any new cells are the cancerous ones that triple in number.
The disruption of cell cycle regulation is one of the main features of cancer. The correct option is 1.
The cell cycle is a strictly controlled process that makes sure that cells grow, divide, and are kept in good condition.
This regulating mechanism can be upset in cancer by mutations or changes in the genes responsible for controlling the cell cycle.
The cell cycle typically moves forward through a number of checkpoints that keep an eye on the DNA's integrity, the availability of critical resources, and the signals for cell division.
These checkpoints serve as controls to stop the division of damaged or aberrant cells.
Thus, the correct option is 1.
