•What seven characteristics are unique only to marine mammals—not all mammals? •What two Suborders do we classify Order Carnivora into?

Answers

Answer 1

Answer: PART 1

1. They nurse their young with milk produced by mammary glands.
2. There are international laws and treaties that protect marine mammals.
3. Unfortunately, many marine mammals are considered endangered species and there are still threats to most of their populations, such as illegal hunting, pollution, climate change, and habitat loss.
4. They have adapted to living all or part of their life in the ocean.
5. To keep warm in the ocean, most of them depend on a thick layer of blubber (or fat).
6. To be able to stay under water for long periods, they store extra oxygen in their muscles and blood.
7. They also have more blood than land mammals in proportion to their body sizes, can direct their blood flow to only their vital organs (such as their heart and lungs), and can slow their heartbeat down so they are using less oxygen in a dive.

PART 2
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Cetacea The Order Cetacea is the group of marine mammals that includes the cetaceans - the whales, dolphins andporpoises.There are 86 species of cetaceans, and these are divided into two suborders - the mysticetes (baleen whales, 14 species) and odontocetes (toothed whales, 72 species).

What evidence of body segmentation do lancelets display?

Answers

Lancelets have a somewhat fish-like body. However, the don't have fins or any other limbs. They are not good swimmers, and have a relatively poorly developed tail. Moreover, they do not possess a true form of a skeleton, they just have some gill slits, mouth and that tail I already mentioned.

I will give out 90 points. Please answer!!DNA Polymerase is used to (select all that apply) the answer is not just “synthesize the daughter strand)
-“read” the template strand
-synthesize the daughter strand
-unzip the template strand
-cut the template strand
-cut the daughter strand

IS THE ANSWER 2-5 and not 1??

Answers

The answer is number 4 hope this helps

Final answer:

DNA Polymerase 'reads' the template strand and synthesizes the daughter strand during DNA replication. It does not unzip or cut the template or daughter strands.

Explanation:

DNA Polymerase has specific functions during DNA replication, a process that occurs prior to cell division. Out of the given options, DNA Polymerase is responsible for two actions:

"Read" the template strand: DNA Polymerase 'reads' the DNA sequence in the 3'-to-5' direction and synthesizes the new DNA strand in the 5'-to-3' direction.
Synthesize the daughter strand: DNA Polymerase helps in the synthesis of the new DNA strand (known as the daughter strand) by adding nucleotides to the 3' end of the growing DNA chain.

However, DNA Polymerase does not 'unzip' the template strand, this is the job of another enzyme called DNA helicase. Likewise, DNA Polymerase does not cut the template or the daughter strand. Thus, answers 3, 4, and 5 are incorrect.

What is speciation? A.the process by which new species are formed

B.the mutations that take place in an organism’s DNA

C.the way that most species become extinct

D.the adaptations that help an organism fit into its environment

Answers

The answer is A. Speciation is the process by which new species are formed. It is an evolutionary process where certain biological populations evolve to new distinct species. It was the biologist Orator F. Cook who first coined this term. There are types of speciation namely sympatric, parapatric, peripatric and allopatric.
