What are two examples of adaptations used by animals that live in aquatic biomes?
Answers
Answer: Common oceanic animal adaptations include gills, special breathing organs used by some oceanic animals like fish and crabs; blowholes, an opening on the top of the head that's used for breathing; fins, flat, wing-like structures on a fish that help it move through the water; and streamlined bodies.
Explanation: Hope this helps :)
The two examples of adaptations used by animals that live in aquatic biomes are gills and webed feet. The correct option is D.
What is adaptation?A structural adaptation is one that is physically a part of the organism. Another type of adaptation is behavioural, which modifies how an organism reacts to its surroundings.
Aquatic animals have adapted by, among other things, having stream-lined bodies that make swimming easy for them.
Their respiratory system is made up of gills. Fish have many different types of fins, including pectoral, and caudal fins, which serve as their locomotory organs.
There are two different kinds of aquatic ecosystems: freshwater and marine. These aquatic adaptations include: inside human bodies, there are specific air spaces.
The fins are present. Oil droplets on microscopic plants keep them floating.
Thus, the correct option is D.

In one experiment, the heart rate of a mollusk at rest was measured at 0.3 cycles/s. How many times did the mollusk's heart beat in 1 min?
Answers
Answer:
18 times
Explanation:
Heart rate = 0.3 cycles/s
Heart rate = [tex]\frac{number of cycles}{time}[/tex]
number of cycles = heart rate x time
But, 1 min = 60 seconds
⇒ number of cycles = 0.3 x 60
= 18
Thus, the number of times that the Mollusk's heart beat in 1 min is 18.

The central dogma describes which of the following?
the process by which enzymes are modified after translation
the way DNA is replicated
the flow of genetic information
the way RNA is used as a template to make DNA
Answers
Answer:
The correct answer is - the flow of genetic information.
Explanation:
The process includes the flow of genetic information or instructions encoded in DNA used to make or turn to a final product that can be DNA or protein, known as the central dogma.
Mostly central dogma term use for the protein synthesis from the DNA that takes place in the two steps, transcription is the first converts DNA into RNA and the second translation that converts product of the first step that is RNA into Protein. DNA → RNA → protein.
Thus, the correct answer is - the flow of genetic information.
The central dogma describes the flow of genetic information. The correct option is C.
A key idea in molecular biology known as the core dogma outlines how genetic information moves through cells. It says that RNA is translated into proteins from transcribed DNA.
This idea emphasises how genes are expressed and proteins are made in living things by sequentially transferring genetic information from DNA through RNA to proteins.
The fundamental dogma excludes DNA replication, the reverse transcription of RNA into DNA, and the process of post-translational enzyme modification.
Thus, the correct option is C.

The area of the picture highlighted by the green square is a monomer of nucleic acids(DNA/RNA). Which of the following is the name for that monomer?
A. phosphate backbone
B. thymine
C. nucleotide
Answers
Answer:
C. Nucleotide
Explanation:
There are four types of biological molecules existing in nature. These are: carbohydrates, proteins, lipids, and nucleic acids. Nucleic acids are biological polymers made up of monomeric units called NUCLEOTIDES.
A nucleotide as depicted in the attached image is a molecule made up of three components namely; Penrose sugar, phosphate group, and nitrogenous base (adenine, guanine, cytosine and thymine). Based on the image in this question;
A represents ADENINE
S represents SUGAR
P represents PHOSPHATE GROUP
Hence, the monomer is a NUCLEOTIDE.

Answers
Answer:

Explanation:
If you use a punnet square with Rr x rr you will get 50% white
50% of the offspring should have white flowers when we cross a hybrid genotype for red flowers with pure recessive for white flowers shown in the Punnett square. So, the correct option is C.
What is Punnett square?Punnett square is defined as the diagram that represents the possible genotypes of the offspring developed after a reproductive event. It was first developed by geneticist Reginald Punnett where the possible genotypes of the offspring are represented in a tabular form with each box in the table representing an event of fertilization.
For above given example,
Rr genotype represents the red flowers.
rr genotype represents the white flowers.
The Punnett square will be:
R r
r Rr rr
r Rr rr
So, 50% have red flowers while 50% have white flowers.
Thus, the correct option is C.

You observe two distinct behavioral strategies among flocks of house sparrows. In one strategy, individuals (producers) search for food patches. In the other strategy, individuals (scroungers) wait for producers to find food and then feed in the patches found by the producers. The relative frequency of these strategies differs in flocks, and you observe that the scroungers have high fitness (a high feeding rate) when they are rare in a flock and low fitness when they are common in a flock. What is one possibility for the persistence of the two phenotypes in this population
Answers
Answer:
Frequency-dependent selection
Explanation:
Frequency-dependent selection is a type of natural selection where the fitness or reproductive success of a particular phenotype/genotype in the population is dependent on its frequency in the population. This type of natural selection can be both positive or negative. Frequency-dependent selection is a critical process that helps to maintain the genetic variability at population and species levels. A known example of frequency-dependent selection (positive) is the mimicry of butterflies, where selection can favor non-poisonous butterflies that show the same colors as poisonous butterflies.

Given these terms related to bats, match the term to the level of biological organization.all little brown bats
Answers
Answer: population: The bat species of North America
community : a little brown bat
organism: bat
Explanation:
Here, the population of the bat resides in the North America in the houses, trees and buildings they hide in the caves in winters for hibernation. Inside the cave they form a bat community here the organism is bat. These bats are threatened in numbers due to white nose syndrome. The white nose syndrome is the fungal growth on the wings and muzzles of the bats. The fungus affects the bats during hibernation, when the bats trying to save their energy by reducing their metabolic rate. It is transferrable from one bat to another thus can infect the entire population of bat. It is a dangerous disease.
Which one of these is not a human effect on the water cycle?

Answer:
Precipitation is increasing in deserts due to an increase in water use
Explanation:

The one that is not a human effect on the water cycle is precipitation is increasing in deserts due to an increase in water use. The correct option is B.
What is the water cycle?The continual movement of water on, above, and below the Earth's surface is referred to as the water cycle, also known as the hydrologic cycle or the hydrological cycle.
One of the most essential elements of human life is water. There is water all over. It passes through your house as well as rivers, mountains, lakes, and oceans. Without water, neither humans nor any other species could survive.
In the majority of deserts, the air's moisture content is very low. In the dry air, light raindrops frequently evaporate before they can reach the ground. Rainstorms can occasionally appear as ferocious cloudbursts.
Therefore, the correct option is B. Precipitation is increasing in deserts due to an increase in water use.
