How many anatomical characteristics do Cetaceans share with Mammals?
Answer:
Anatomy suggests that Cetaceans are more closely related to mammals than fish since they share more similarities with the mammals, such as a 4-chambered heart and lungs. What does anatomy say about the ancestry of Cetaceans?
Explanation:
Hope it helps! Correct me if I am wrong :>
Anatomy suggests that Cetaceans more closely resemble mammals. Cetaceans have a 4-chambered heart, lungs to breathe, giving birth to young ones, mammary glands, endothermic, etc.
What are Cetaceans?Cetaceans can be called aquatic mammals and it includes whales, dolphins, etc.
These are one of the most distinctive and highly specialized orders of mammals.
They are more likely to have anatomical characteristics of mammals than fish. As they have a 4-chambered heart, are endothermic, give birth to young ones, and have mammary glands, these are considered under mammals.
Thus, these are the characteristics that Cetaceans share with mammals.

Define the following :
-self-concept
-self motivation
-volunteer
-self-image
-Adolescents
Answer:
Self-concept is the set of ideas that make up the image that each person has about himself, that is, it is the opinion that an individual forges about himself. That sentence carries a certain value judgment. Self-concept: set of elements that a person uses to describe himself. Self-motivation is giving the reasons, the drive, the enthusiasm and the interest that provoke a specific action or a certain behavior. Volunteer is the person who, by his own choice, dedicates part of a part of his time to solidary, altruistic action, without receiving remuneration in return. The stage that comes after childhood and that ranges from puberty to the full development of the body is known as adolescence. Self-image is the value we have in relation to ourselves.
Explanation:
Self-concept: set of elements that a person uses to describe himself. The ability to motivate yourself is what is known as self-motivation. This is an important skill, as it encourages people to continue progressing even in the face of setbacks, to seize opportunities and to show commitment to what they want to achieve. Volunteer is that person who joins an organization in a free way to help altruistically in various social activities. When we speak of self-image we refer to the image that our subconscious has of ourselves. Adolescence is understood as the period of human development after childhood and before adulthood, in which the biological, sexual, social and psychological changes necessary to form a socially mature individual and physically prepared for reproduction take place.

Use the following terms: Natural Selection, Variation, Mutation, Adaptation, Overproduction, Descent with Modification, Evolution, Population, Species, Heritability, and Fitness and show the relationship between them that lead to the result, Evolution.
Answer:
Variations in species led to evolution. Some species have desirable traits that are beneficial to their survival. Some species have undesirable traits that are not beneficial to their survival. E.g. peppered moths are not easily seen by predators because they camouflage with the bark, black moths are easily seen by predators so they are eaten. In the example mentioned, the peppered moths have a beneficial trait, this is also known as fitness, because the organism is fit for survival, unlike the black moths. Overtime the population of black moths decreases because they are not fit for survival, therefore the black moths cannot reproduce offspring that also have black wings. However, the population of peppered moths increases, because the peppered moths are able to reproduce offspring. Those offspring inherit their parents' traits, which make them have peppered wings too.

Imagine that you find a layer of rock containing many fossil clams. The layer of rock is 50 km from the ocean. The fossils are about 5 million years old. Clams usually live in shallow ocean water. Based on the fossils, what can you guess about the environment in this area 5 million years ago?
Answer:
No ocean is present 5 million years ago.
Explanation:
There is no ocean or sea in this area 5 million years ago because the land is present where these fossils live but with the passage of time the geography of that place changes and the ocean covered the area and these fossils remain below the ocean inside the layer of land. So we can conclude from the presence of these fossils that there is no ocean present in these regions 5 million years ago .
The area that contains many fossil clams used to covered with ocean water 5 million year ago
Clams are the the variety of shel-fish that are usually found in shallow water and are important to maintain the web of the ecosystem
5 million years ago the area of 50 km was covered with shallow water range but with the time and environmental change area with clams got vanished and with time changed into fossil.
Therefore, the area of 50 km used to covered with ocean water 5 million year ago.

Transcribe this sequence of DNA to RNA: ATTGAC
Answer:
your can write fast summary about it if you have test or smth
First, think about which base pairs arise in complementary strands of DNA:
DNA → DNA
adenine → thymine (A → T)
thymine → adenine (T → A)
cytosine → guanine (C → G)
guanine → cytosine (G → C)
However, mRNA does not consist of the same four bases as DNA. While DNA has the ATCG nitrogenous bases, RNA replaces thymine with uracil, making its bases AUCG.
So, that means that whenever DNA has adenine, instead of pairing this with thymine, RNA will use uracil instead.
DNA → RNA
adenine → uracil (A → U)
thymine → adenine (T → A)
cytosine → guanine (C → G)
guanine → cytosine (G → C)
Giving us the corresponding sequence:
UAGGCUAA
Transcribe this sequence of DNA to RNA: ATTGAC
How does population growth differ between developing countries and developed countries? What might account for these differences?
Answer:
Developing countries have a low life expectancy because things like water might be populated/scarce, the air may be polluted and immunisation might not be possible. But developed countries are more likely to have safe drinking water, and vaccines.

Which of these statements is true about internal respiration?
[a] Production of ATP
[b] Exchange of gases between the bloodstream and tissue cells
[c] Exchange of gases between alveoli and the bloodstream
[d] Breathing between the atmosphere and the alveoli
Answer:
c
Explanation:
because I don't know how to exam tho
Exchange of gases between alveoli and the bloodstream ( Option C )
Internal respiration is the process of exchanging gases ( i.e. carbon dioxide and oxygen ) between the bloodstream and the alveoli of an organism. as seen in human.
Internal respiration ( exchange of gases) occurs between Alveoli and the bloodstream. While External respiration occurs between the atmosphere and the alveoli.Also the Alveoli is important in both external and internal respiration. but for internal respiration, the alveoli exchanges gases with the bloodstream before it is passed to the internal issues .
Hence we can conclude that the true statement about internal respiration is ; Exchange of gases between the alveoli and the bloodstream.

Which phrase, if placed in box X, would correctly complete the flowchart shown below?
Decreased concentration of oxygen in leaf cells
Increased use of starch in root cells
Increased concentration of glucose in leaf cells
Decreased ATP in root cells
Answer: Increased concentration of glucose in leaf cells
Explanation:
Based off the flowchart, the process that it's describing is photosynthesis because during this process sunlight and CO2 are taken in by a plant to produce glucose. If we are exposed to sunlight and are increasing the use of CO2, then there must be a higher concentration of glucose in the leaf cells. Glucose is a product of photosynthesis.
