Answer: All organisms need energy. ...
Autotrophs (producers) use energy directly from the sun or from chemicals to produce organic molecules. ...
Heterotrophs (consumers) obtain energy by consuming other organisms. ...
The flow of energy in an ecosystem can be represented with a food chain or food web
Explanation: A heterotroph is an organism that eats other plants or animals for energy and nutrients. The term stems from the Greek words hetero for “other” and trophe for “nourishment.” Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs. A consumer is an organism that eats other organisms or organic matter instead of producing its own nutrients or obtaining nutrients from inorganic sources. Consumers are also called heterotrophs, or other-feeders Producers
Producers: Producers are organisms that get their energy directly from the Sun. Their cells are able to turn sunlight into food through a process called photosynthesis. Organisms, such as humans, take in "substrates" such as glucose, in our food. During a process called respiration, we react 4these substrates with oxygen to give carbon dioxide and water; this takes place in the mitochondria of our cells.
Explain why hormone-producing cells are always located in close proximity to
capillaries.
Answer:
Hormone Signaling The hormones then diffuse to the bloodstream via capillaries and are transported to the target cells through the circulatory system. This allows hormones to affect tissues and organs far from the site of production or to apply systemic effects to the whole body.

A typical virus is made up of 2 parts. Check all that apply.
A) Golgi Body
B) Nuclear envelope
C) Nucleic Acid
D) Capsid
Answer:
C) Nucleic Acid
D) Capsid
Explanation:
A virus is structure that is dependent on a living host to replicate itself. Viruses are majorly pathogenic in nature and have a structure that is made up of two parts namely: nucleic acid and capsid.
The nucleic acid, which can either be RNA or DNA holds the genetic information of the virus while the capsid is a protein coat that enclosed and protects the virus' genetic material. The capsid is also used during the infection life cycle of a virus where it helps the virus to attach to receptor cells on the host's cell membrane.

Why do deserts tend to form on land at latitudes of 20-30 degrees north and south?
Answer:
Deserts can form even on tropical coasts beside cold ocean currents, such as the west coast of South America. The currents cool the air, which then rises and warms as it moves over land, drawing up moisture that is later precipitated as the air moves farther inland.

Select ALL the correct descriptions that help to define luminosity.
A. How much energy is emitted per second
B. How much surface area the object has
C. The amount of brightness of an object
D. The color emitted by the start
The correct descriptions that help to define luminosity are How much energy is emitted per second, How much surface area the object has, and The amount of brightness of an object.
What is the energy content of luminosity?An object's luminosity, which is the quantity of energy it emits over a predetermined period, is a measurement of its inherent brightness. Since it simply measures the object's power output, it can be expressed in units like Watts.
What factors affect luminosity?A star's luminosity, or the total amount of energy it emits each second, is determined by two factors: The stellar photosphere's "Effective Temperature," T. the star's total surface area, which is influenced by its radius, R.
What three things have an impact on luminosity?The size, temperature, and distance of a star are the three variables that determine how bright it seems to us on Earth. The brilliance of a star is measured by its magnitude.

Fenómeno que consiste na combustão de grandes áreas florestais e conduz à libertação de grandes quantidades de CO2 para a atmosfera.
Answer:
Wildfires.
Explanation:
Wildfires is the phenomenon that causes combustion of large forest areas and leads to the release of large amounts of CO2 into the atmosphere. Wildfire occurs naturally as well as carelessness of humans that leads to the destruction of large area of forest and the habitat of wild animals also destroyed which compels them to migrate from that region. This wildfires produced high amount of carbondioxide gas in the atmosphere that is the main cause of air pollution.

Does the Second Amendment need to be "revisited" in 2021? yes and why?
I need help pleasee
Answer:
It needs to be revisited because of the random acts of violence that it enables.
Explanation:
People that have access to weapons of mass destruction use them to kill people for no reason. For example, the sandy hook shooting, the recent Stoneman Douglas shooting, and the Christchurch shooting. All these shootings could have been prevented if there was stronger gun control. If people did not have access to automatic firing machine guns, less people would have died.

4. Cross a white bull with a white cow. Show the Punnett Square:
% Red Cow
% Roan Cow
% White Cow
Answer:
100% white cow
Explanation:
This question involves a single gene coding for skin color in cattle. The allele for red color (R) is codominant with the allele for white color (r). Hence, the roan cattle (Rr) will possess both red and white coloration.
According to this question, a white bull (rr) is crossed with a white cow (rr). Each parent will produce the "r" gamete, which when used in a punnet square will produce all WHITE COWS i.e 100% white cows. See punnet square attached.
Answer:
white cow

Which of the following would cause an error in DNA replication?
A. DNA polymerase pairing A with G
B. DNA ligase connecting chunks of DNA
C. Helicase making a replication fork
D. DNA polymerase checking the DNA
Answer:
A. DNA polymerase pairing A with G
Explanation:
Adenine (A) always pairs with thymine (T), and cytosine (C) always pairs with guanine (G).
DNA polymerase pairing A with G would cause an error in DNA replication. The correct option is A.
An error in DNA replication occurs when an incorrect nucleotide is inserted during the replication process.
DNA polymerase is responsible for synthesizing a new DNA strand by adding complementary nucleotides to the existing template strand.
It ensures the accuracy of replication by matching each nucleotide with its complementary partner (A with T and G with C).
If DNA polymerase pairs A with G instead of A with T, it results in a mismatched base pair.
This is considered an error in DNA replication since it introduces a mutation in the newly synthesized DNA strand.
The fidelity of DNA replication relies on the correct base pairing and proofreading mechanisms of DNA polymerase to minimize errors and maintain the integrity of the genetic information.
Thus, the correct option is A.
