If a bat, an alligator, and a bird evolved from a common ancestor, most likely can be concluded that they have similar anatomical structures. Thus, option C is correct.
What are the different structures of animals?Structures of animals that have different appearances and functions but seem to have evolved from the same body part in a common ancestor. This can be found in Cat's leg and human arms.The structure do not need to look the same or perform the same functions.
The analogous structure evolve in different species living in two different geographic location with similar environmental conditions. Thus, the analogous structures have similar function and purpose but since they have not evolved from the same ancestor their structure vary a lot for example – wings in both birds and butterfly are meant for flight but their structure is entirely different.
The arrangement of bones is identical in all three organisms. This effectively means that all these organisms gradually evolved from a common ancestor.
Therefore, If a bat, an alligator, and a bird evolved from a common ancestor, most likely can be concluded that they have similar anatomical structures. Thus, option C is correct.

Answer:the answers are a and d
Explanation:
I did the test sorry if wrong
In the given image, it is showing that plants use carbon dioxide gas to make sugars during photosynthesis. The correct option is D.
What is carbon cycle?The carbon cycle is nature's method of recycling carbon atoms, which travel from the ambience into Earth's living organisms and then back into the atmosphere. The majority of carbon is stored in rocks and sediments, with the remainder in the ocean, environment, and living organisms.
Plants consume carbon dioxide and sunshine during photosynthesis to produce fuel i.e., glucose and other sugars for the construction of plant structures. The fast biological carbon cycle is built on this process.
Thus, the correct option is D.

[tex]\purple{\tt{\huge{Answer}}}[/tex]
substrate specificity. The active site of an enzyme is very specific to its substrates as it has a very precise shape. This results in enzymes being able to catalyze only certain reactions as only a small number of substrates fit in the active site. This is called enzyme-substrate specificity.
Answer:substrate specificity. The active site of an enzyme is very specific to its substrates as it has a very precise shape. This results in enzymes being able to catalyze only certain reactions as only a small number of substrates fit in the active site. This is called enzyme-substrate specificity.
Explanation:Enzymes and substrates share specificity in that an enzyme will only react with a specific substrate • This is because the active site is complementary in both shape and charge to a given substrate • The model by which this is known is ‘lock and key’ as the substrate is a precise structural fit for the enzyme, much like a lock and key • When the enzyme and substrate bind, they form an enzyme-substrate complex, before the substrate is catalytically converted into a product

While performing strenuous exercise, a person may experience a temporary shortage of
oxygen. As a result, anaerobic respiration supplies the required energy.
What is an end product that will build up in the person's muscles?
A. ethyl alcohol
B. glucose
C. lactic acid
D. pyruvate
Answer:
C. lactic acid
Explanation:
"Lactic acid" build-up in the muscles occur when a person does an "anaerobic exercise," specifically high-intensity ones. Due to lack of oxygen going to the muscles (temporary), "glycolysis" occurs. This means that glucose will be used in order to provide the energy needed. This process produces lactic acid as an end-product. This makes the muscles "sore," thus, it is important to have rests per week in order to eliminate lactic acid.
Where does carbon dioxide end up?

What is Respiratory system?The respiratory system is defined as the network of organs and tissues that help us breathe which includes the airways, lungs, and blood vessels. The muscles that power the lungs are also part of the respiratory system where these parts work together to move oxygen throughout the body and clear out waste gases like carbon dioxide.
Respiratory system works in that way with the immune system by keeping the human from getting sick by bacteria and viruses are removed or swallowed by mucus, while the cilia act like a filter, trapping dust and pollen in the nose.

Your lab is working on sequencing a new plasmid. Before starting, you all decide to guess how many base pairs you think the new plasmid has. The lab members' guesses are 4,005; 4,006; 4,007; and 4,010. It turns out the plasmid has 7,968 base pairs. Accurate Precise Neither Both
Solution :
In this question we have to determine whether the statement given in the question is accurate or precise or both or neither of them.
In the question it is given that the lab members are making a guess about how many base pairs will the new plasmid will have. Their random guesses of base pairs are 4,005; 4,006; 4,007; and 4,010. But in actual, the new plasmid has 7,968 number of base pairs.
Therefore, according to it, the data in the statement is precise but it is not accurate.
Precision refers to the degree of the reproducibility of measurements even if the values varies from accepted values. And accuracy shows how much close the measurement is to the accepted or the known value.
We say that we have a precise data on our hands and not an accurate one
Option B
AccuracyQuestion Parameters:
The lab members' guesses are 4,005; 4,006; 4,007; and 4,010.
Generally, accuracy shows how close a size is to a regarded or established value, whilst precision in facts capability the degree of reproducibility of the measurements. Measurements that are each specific and correct are repeatable and very close to genuine values.

3. Which is an example of genetic biodiversity?
a. Different skin color within a species
b. Different types of species in an ecosystem
C. Every organism has the same genetic sequence
d. All populations look identical within a species
Answer:
A
Explanation:
Has to be the same family to be genetic and you have to find which has the most variety
Different skin color within a species is an example of genetic biodiversity. Therefore, option (A) is correct.
What is genetic biodiversity?
Genetic biodiversity refers to the variety of genes and genetic traits that exist within a population or species. It is a fundamental aspect of biodiversity, as it underpins the ability of species to adapt to changing environmental conditions and to maintain resilience in the face of threats such as disease, climate change, and habitat loss.
Genetic biodiversity arises from mutations, genetic recombination, and other processes that generate new genetic variation within populations. This diversity provides the raw material for natural selection to act upon, allowing organisms with advantageous traits to survive and reproduce.
Genetic biodiversity is important for ecosystem functioning and for the conservation of species, as it helps to ensure that populations are able to adapt to changing conditions and maintain their long-term viability. The loss of genetic biodiversity can have significant negative impacts on populations and ecosystems, making it an important focus of conservation efforts.

Which of these factors affects how fast a sound wave moves? the kind of material it is moving through the kind of material it is moving through the amplitude of the sound wave's vibrations the amplitude of the sound wave's vibrations the wavelength of the disturbance in the medium the wavelength of the disturbance in the medium the type of motion that caused the sound wave to form the type of motion that caused the sound wave to form
Answer:
the kind of material it is moving through
Explanation:
Sound wave is a type of mechanical wave, which requires a medium to travel, unlike longitudinal waves that can travel through vacuums. Since, sound waves travel through mediums, the KIND OF MEDIUM/MATERIAL it is traveling through has a role to play on how fast it moves.
Sound waves move faster in materials whose molecules are closely packed together than those with loosely packed molecules. This is why sound waves naturally travel faster in SOLID materials. Therefore, the the kind of material the sound wave is moving through affects how fast it moves.
