Which of the following best identifies a way in which organs in an organism are similar to organelles in a cell?
A. Both are made of tissues.
B. Both carry out specific functions.
C. Both carry out chemosynthetic reactions.
D. Both are found in single-celled organisms.
Answer:
A
Explanation:
Both are made of tissues.
The organs in an organism and organelles in a cell both are similar as they both are made up of tissue. Thus, option A is correct.
What is tissue?The tissue is defined as a group of cell added together to form a tissue present in body and plays a vital role in covering of all internal as well as external area and organs of body, hollow organs and body lines cavity.
The structure of epithelial cells are they combined together by fitted junctions as well as adhering junction and attached to extra cellular matrix.
Tissue is the compact structure of cell and later tissue combined together to form organ and than organ system is formed to perform various functions of the body.
Therefore,the organs in an organism and organelles in a cell both are similar as they both are made up of tissue. Thus, option A is correct.

What forms as a result of the wind's frictional force on water?
Responses
deep sea currents that move in a path similar to the wind currents
surface currents that move in a path similar to the wind currents
deep sea currents that move in a path opposite to the wind currents,
surface currents that move in a path opposite to the wind currents
Answer:
air or co2
Explanation:
if the wind force is going to be pushed. by air whoch cretaes an atmosphere with water
Answer:
The correct answer is - waves.
The frictional force of the winds is the force with which the winds influence a surface. The smoother a surface is the lesser the friction, and vice versa. The water is a smooth surface, so the winds frictional force is not very big on it, but it is big enough to cause the occurrence of the waves. By constantly influencing the water with their frictional force the winds manage to move and disrupt the surface of the water, with the end result being the waves. Depending on the strength of the winds and the frictional force accordingly to that the waves can be very small, only few mm in height, or can be up to several meters in height.

how does the organization of the organism work together to function properly
Answer:
Like cells and tissues, organs seldom work alone. They "cooperate" with one another and form specific organ systems. Organ systems are the fourth level of organization in living things. An organ system is a group of organs working together to perform a specific function for the organism.
Which fossil species was separated from the giraffe in the more distant past (longer ago)?
Answer:
Petron
Explanation:
Beavers, large members of the rodent family in North America, are often referred to as “ecosystem/keystone engineers” by wildlife managers. Ecosystem engineers are described as animals that create, alter, or destroy a habitat. Beavers contribute to river ecosystems by bringing down old and dead trees along riverbanks. They use these trees to make their dams. Although these dams are primarily used for protection and food storage, scientists report that these dams change the surrounding environment in different ways.
Given this information, in three to five sentences, describe a potential benefit that beavers contribute to the ecosystem as keystone engineers and describe a plausible impact that the removal of beavers could have on the surrounding ecosystem.
Answer:The potential benefit that beavers contribute to the ecosystem include sources of food and habitat for some animals.This consists of all the organisms and the physical environment with which they interact.The removal of the beavers will allow for more oxygen to be present within the ecosystem as a result of increased plant population.

What structures (Homologous, Analogous, or Vestigial) would be most helpful in studying the selective pressures in an environment. Explain.
Answer:
Vestigial structure
Explanation:
Homologous structures are physical structures such as organs or skeletal elements present in numerous species that come from a shared common ancestor. Analogous structures are bodily structures that resemble one another superficially and provide a similar function but have evolved separately and do not come from a shared common ancestor (such as the wings of an insect and bat). One vestigial structure present in humans is the appendix. This organ was once vital in the consumption and digestion of uncooked meat, but no longer serves a function.

Geologists study the solid parts of Earth, the inside of Earth, the forces that affect Earth, and the rocks and minerals that makeup Earth. Hence, options B, C, E, and F are correct.
What are the roles of geologists?Geologists help identify and assess natural resources, such as oil, gas, coal, and minerals, by studying the geology of an area. They also evaluate the environmental impact of resource extraction and develop strategies for responsible resource management.
Geologists create maps of the Earth's surface and subsurface to better understand the distribution of resources, identify potential hazards, and plan infrastructure projects.
They also monitor geologic activity, such as earthquakes and volcanic eruptions, to better understand how the Earth's crust behaves over time. Hence, options B, C, E, and F are correct.
