What happens to daphnia heart rate when the temperature rises ?
Answers
Answer:
It'll receive less oxygen
Explanation:
Less oxygen would be present in the warmer water, which could be one explanation for Daphnia's heart rate rising with temperature. Because there may not be enough oxygen in the blood, the heart would have to work harder to pump blood throughout the body.
Blood is a fluid connective tissue that flows through the heart and blood
vessels. This ability to flow allows blood to perform what function?
O A. Release substances for the body to access for energy
B. Cushion and protect internal organs to prevent injury
C. Transport nutrients and oxygen and carry away wastes
OD. Form a protective barrier to prevent water loss
Answers
Blood, as a fluid connective tissue, has the crucial role of transporting oxygen and nutrients to cells around the body whilst also carrying away waste products, like carbon dioxide. It circulates throughout the body, allowing this process to reach every cell. Other functions such as cushioning organs and forming a protective barrier are not its main purpose.
Explanation:Blood is indeed a fluid connective tissue that has the crucial function of transporting various substances throughout the body. The correct answer to your question is C. Transport nutrients and oxygen and carry away wastes.
This happens because the heart pumps the blood, which then travels through the blood vessels, allowing it to reach every part of our body. This delivery system carries oxygen and nutrients essential for the cells to function. At the same time, it picks up waste products, like carbon dioxide, from the cells which it then removes from the body.
While the blood does perform other functions, these aren't represented by the other options. For example, it does not primarily serve to cushion organs, form a protective barrier, or release substances for energy - these are not its main functions.

The Barton Springs salamander is an endangered species found only in a single spring in the city of Austin, Texas. There is growing concern that a chemical spill on a nearby freeway could pollute the spring and wipe out the species. To provide a source of salamanders to repopulate the spring in the event of such a catastrophe, a proposal has been made to establish a captive breeding population of the salamander in a local zoo. The zoo was asked to provide a plan for establishing this captive breeding population, with the goal of maintaining as much of the genetic variation of the species as possible in the captive population.
What factors are likely to lead to a loss of genetic variation in the captive population?
a. increased rate of mutation
b. a founder effect
c. reduced genetic drift over time
d. a lack of inbreeding
What strategy would likely be effective in mitigating the loss of genetic variation in the captive population?
a. keeping the sex ratio as close to 50:50 as possible
b. stopping gene flow to and from the captive population
c. regularly mating individuals that are related
d. keeping the captive population as small as possible
Answers
Answer:
1) Option b is correct. a founder effect
2) Option a is correct. keeping the sex ratio as close to 50:50 as possible
Explanation:
The exposed situation is an example of an ex-situ conservation program. These programs are planned to keep and restore the population of species that are in danger of extinction. There are many challenges associated with captivity, and one of them is related to maintaining genetic diversity in the population.
1) Introducing a few animals of an endangered species into the zoo might be considered an example of the founder effect. Just a pregnant female is enough for it to occur. And the most significant problem associated with this event is the loss the genetic diversity or variability. When breeding animals in captivity there is a high risk of losing some genes and fixating others, due to inbreeding.
Genetic drift is the random change that occurs in the allelic frequency of a population through generations. The magnitude of this change is inversely related to the size of the original population. These changes produced by genetic drift accumulate in time. Eventually, some alleles get lost, while some others might set. Genetic drift affects a population and reduces its size dramatically due to a disaster or pressure-bottleneck effect- or because of a population split -founder effect-. In founder effect, a new population originates when a few individuals, coming from a bigger-sized population and carrying their genes, settle down in a new area and reproduce. This small population might or might not be genetically representative of the original one. Some rare alleles might be exceeded or might be lost by complete. Consequently, when the small population increases in size, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced, and there exists the possibility of developing a peculiar allelic composition. When the number of individuals that originated the new population is low, the founder effect will be very extreme because the genetic drift effects are inversely proportional to the original number of individuals.
2) When selecting the animals that are being kept in captivity, it is significant to consider a few aspects concerning genetic diversity maintenance. The main objective is to prioritize the original genetic material.
To get founder individuals that get to represent the maximum genetic variability of the population, or among population if possible. The sex proportion of the founder individuals should always be 1:1 or 50:50. This ratio is important to keep genetic variability, especially because many males in captivity might have reproductive problems. To keep diversity, females need to mate with different males, and not just a few of them. Animals should be subadults reaching their sexual maturity.When mating animals, they should be as different as possible to decrease the possibility of a common ancestor among the couple.29.

This is an example of exponential growth.
Exponential growth refers to a pattern of growth where the quantity or size of something increases at an accelerating rate over time.
In the given scenario, Brain has one son, two grandchildren, and three great-grandchildren.
Each generation is producing more offspring, resulting in a rapidly increasing number of descendants.
The progression from one generation to the next demonstrates exponential growth because each subsequent generation adds more individuals than the previous one.
As the generations continue, the number of descendants grows exponentially larger.
Exponential growth can be observed in various natural and human-made systems, such as population growth, compound interest, and the spread of infectious diseases.
In this case, the number of descendants in Brain's family tree follows an exponential pattern, as each new generation multiplies the number of offspring, leading to a significant growth rate.
Therefore, the example given aligns with the concept of exponential growth.

Answers
After a few hours, the cells of each sponge would re-aggregate and form three new sponges.
We can reach this answer because:
The sponge is a multicellular organism with little cell differentiation.The surface of sponge cells has a group of glycoproteins, which allow communication between all the cells in a sponge.These proteins are transmembrane receptors, which emit signals responsible for the cell adhesion process.The cell adhesion process allows the cells in a sponge to regroup if they are separated.In this case, if three sponges had their composition sieved and mixed, the glycoproteins of their cells would allow each sponge to be remade, as there would be communication and a regrouping of the cells of each sponge.

4. The ATP yield from 2 moles of mitochondrial NADH under aerobic conditions in a eukaryotic cell would be: which option is correct a) 1 mole of ATP b) 2 moles of ATP c) 3 moles of ATP d) 4 moles of ATP e) 6 moles of ATP
Answers
The ATP yield from 2 moles of mitochondrial NADH under aerobic conditions in a eukaryotic cell is approximately 4 moles of ATP.
During oxidative phosphorylation, each mole of NADH can generate around 2.5 to 3 moles of ATP. Therefore, for 2 moles of NADH, the total ATP production would be in the range of 4 to 6 moles of ATP. While the more precise estimate falls within the 4 to 6 moles range, the closest option provided is 4 moles of ATP. It is important to note that the exact ATP yield can vary depending on factors such as the efficiency of the electron transport chain and the specific conditions within the cell.Since there are 2 moles of mitochondrial NADH, the total ATP yield would be around 4 to 6 moles of ATP. However, the most accurate option among the given choices is 4 moles of ATP.

B) Part of the chromosome breaks away, but reattaches in inverse orientation.
C) An extra chromosome is added, causing mismatching of the chromosome pairs.
D) There is a misreading of the base pairs during translation.
Answers
Answer:
C) An extra chromosome is added, causing mismatching of the chromosome pairs.
Explanation:
Mutation is any change, whether big or small, that occurs in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs.
According to the question, frameshift mutation is a mutation that causes the normal reading frame of the nucleotide sequence to be altered. It is caused when an extra chromosome is added (insertion) or when one chromosome is removed (deletion). In either way, there will be a mismatch or alteration in the chromosome pair, hence affecting the reading of the nucleotide sequence.
In frameshift mutation, the insertion or deletion causes the
normal CODONS (triplet nucleotide) to be missing or incomplete, hence, disrupts the manner at which the reading takes place (reading frame). Note, frameshift mutation only occurs as a result of insertion or deletion of chromosomes/bases that are not multiples of three that can maintain the normal reading pattern/frame.
