5. Which of the following correctly lists the kingdoms of life scientists currently use? (1 point) Terapoda, Aminota, Mammalia, Carnivore, Felidae kingdom, phylum, class, order, family, genus, species Bacteria, Archae, Eukarya Eubacteria, Archaebacteria, "Protista," Fungi, Plantae, Animalia Would someone please help me out with this?

Answers

The option which correctly lists the kingdoms of life that is currently being used by scientists is:  –Eubacteria, Archaebacteria, "Protista," Fungi, Plantae, Animalia– 

When Carl Linnaeus initially developed the current system of classification, he named two kingdoms, Plants and Animals. But with the use of the microscope, scientists have come to discover some new organisms. These discoveries have led to the currently used 6-kingdom system of classification.

The Kenyanthropus platyops find at Lake Turkana, Kenya, although still debated, could mean that __________. a) Early humans had a diverse diet b) Early humans had a limited diet c) Early humans lived in caves d) Early humans were primarily herbivores

Answers

The Kenyanthropus platyops find at Lake Turkana, Kenya, although still debated, could mean that:

a) Early humans had a diverse diet

The discovery of Kenyanthropus platyops suggests the possibility of a more diverse diet among early humans. However, it's important to note that the interpretation of this find is still a subject of debate in the field of paleoanthropology.

Need some help! Will appreciate the fastest answer. Thnx in advanced!1) What do B cells do?

2) Why do doctors recommend that people get a new flu shot every year?
a. the flu virus becomes immune to the vaccine
b. the vaccine wears out over time
c. your body eliminates the vaccine
d. the flu virus changes every year

3) Antibodies do which of the following?
a. attach to cells with corresponding antigen
b. engulf and destroy pathogens
c. produce antigens
d. produce immature cells that become B cells

I keep getting a D, so if you could kind of explain it to me as well, that will be great.

Answers

B cells produce antibodies (option C), whereas doctors recommend that people get a new flu shot every year because the flu virus changes every year (Option D).

What is mutation?

Mutation refers to any type of alteration of the genetic material (DNA) in the genome of an organism or virus.

  • Antibodies attach to cells with corresponding antigens (Option A), which is fundamental in immune responses.

  • Antibodies are produced by specific cells of the immune system (B cells).

In conclusion, B cells produce antibodies (option C), whereas doctors recommend that people get a new flu shot every year because the flu virus changes every year (Option D).

B cells make antibodies. That's just what they do.

2 is D. The flu virus constantly mutates, so a new vaccine every year is developed.

Antibodies attach to cells with the corresponding antigen. anti-anti, that's how i remember it.

Why must cells reproduce?

HELP PLZZ :((

Answers

Answer: Cell division is key to life: from the moment we are first conceived, we are continually changing and growing. In order for our bodies to grow and develop, they must produce new cells—and allow for the death of old cells. Cell division is also an essential component of injury repair.

Explanation: have a good day

Cells must reproduce to provide protection for your body.

What is the term for each step in the transfer of energy and matter within a food web?

Answers

The term is known as TROPHIC LEVEL...........

Final answer:

In a food web, each step in the transfer of energy and matter is referred to as a trophic level. These steps provide an illustration of energy flow within an ecosystem, with examples being producers, consumers, and higher-level consumers. The transfer of energy - although more complex - is more accurately depicted in a food web than in a food chain.

Explanation:

The term for each step in the transfer of energy and matter within a food web is known as a trophic level. These are the different steps in a food web or chain at which the transfer of energy occurs. An example of these levels can include producers, primary consumers, and higher-level consumers, each playing specific roles in the overall energy flow.

A food chain is a linear system that offers a simplified view of energy transfer within an ecosystem, while a food web offers a more complex and holistic view of the multiple trophic interactions and energy transfers within an ecosystem.

It is important to mention that energy transfer efficiency influences the structure and dynamics of ecosystems. This is due to the fact that with each energy transfer, some energy is lost, often in the form of heat. This limits the length of food chains within a food web.
