Which statement is supported by this cladogram?
A Hippopotamuses are more closely related to cows than to javelinas.
B Toothed whales are more closely related to mouse deer than to hippopotamuses.
C Javelinas and pigs are more closely related than baleen whales and toothed whales.
D Cows and mouse deer are more closely related than javelinas and pigs.
Answer:
A Hippopotamuses are more closely related to cows than to javelinas.
Explanation:
A cladogram is a branched diagram of characteristics shared by the organisms of a group, that represents the most probable evolutive history of the linage. Cladograms reflect the phylogenetic relationships among groups through phylogenetic trees.
In the phylogenetic tree, the taxonomic groups of interest are located in the extremes of the lines called branches. The ramification point, which is also called "node" or divergence point, represents the location of the most recent common ancestor.
The common ancestor position will determine how related are two species. If they have a recent common ancestor, they are closely related to each other. On the other hand, if the common ancestor is not recent and is located far away in the tree, then the two species will be less related to each other.
A Hippopotamuses are more closely related to cows than to javelinas. TRUE. Hippopotamuses share a common more recent ancestor with cows than with javelinas. This means that the hyppopotamus is more related to cows than to javelinas. The arrows in the cladogram (attached file) show the positions of the common ancestor shared by Hippopotamuses and Cows, and the common ancestor shared by Hippopotamuses and Javelinas.
B Toothed whales are more closely related to mouse deer than to hippopotamuses. FALSE. Tooth whales are more related to the hyppopotamus. Their common ancestor is more recent than the common ancestor between toothed whales and mouse deer. The arrows in the cladogram (attached file) show the positions of the common ancestors.
C Javelinas and pigs are more closely related than baleen whales and toothed whales. FALSE. They are equally related.
D Cows and mouse deer are more closely related than javelinas and pigs.
FALSE. They are equally related.

(b) Explain how the addition of a phosphate group to certain amino acids of Brec likely affects the tertiary structure and function of Brec. Explain how
the addition of a small RNA could prevent the activation of kinase D?
Answer:
Protein phosphorylation can activate/deactivate protein function, while small RNAs can be used for repressing translation of mRNAs through the RNA interference (RNAi) pathway
Explanation:
Protein phosphorylation is one of the most important posttranslational modifications (PTMs) that acts to activate, inhibit, or reversibly switch on/off protein function. Protein phosphorylation confers a reversible and versatile process that cells use to transmit signals and respond to environmental stimuli. This PTM is well known to modify the tertiary structure of the protein and thus activate/inhibit protein functions such as, for example, signaling pathways associated with protein interactions. In consequence, protein phosphorylation can be used by a cell to regulate Brec activity. On the other hand, small non-coding RNAs (ncRNAs) such as, for example, microRNAs (miRNAs), small interfering RNAs (siRNAs), and PIWI-interacting RNAs (piRNAs), are regulatory molecules that bind by complementary base pairing to messenger RNAs (mRNAs) in order to repress translation and/or trigger mRNA degradation through the RNA interference (RNAi) pathway. The RNAi pathway is widely used in molecular biology to silence genes of interest (for example, in this case, the gene that encodes for the kinase D protein).
1. Adding the phosphate group to the amino acid chains is known as phosphorylation. This attachment affects the tertiary arrangement and function of Brec.
Amino acids join together to form the protein that needs to be stimulated and deactivated for proper functioning.Protein phosphorylation is very crucial in post-translation modification.For protein function, it acts as an activator, inhibitor, reversibly on and offs the switch.Phosphorylation assures a reversible process to the cell to transmit signals for the cell functioning.Therefore, Brec activity can be controlled by the phosphorylation of proteins.2. Small RNA's are RNA fragments which is around 150 nucleotide in length.
Functionally significant small RNA's such as siRNAs, microRNAs scaRNAs and many other acts as regulatory molecules which target and adheres to the mRNA transcripts.This binding inhibits the translation process or degrades the mRNA by activating the RNA interference (RNAi) pathway.RNAi pathway is used to suppress the activation of the kinase D.To learn more about phosphorylation and small RNA follow the given link below:

Which of the following describes the effect of global climate change on biodiversity: Rising ocean water temperatures have increased the populations of krill and Antarctic silverfish thus increasing Adelie penguin populations for whom these are food sources. Warm temperatures and more frequent dry periods have stressed frog species such as the coqui making them more vulnerable to a lethal fungal infection thus reducing their populations. The warming of ocean waters in conjunction with increased carbon dioxide dissolving into ocean has resulted in boon for coral reefs which are thriving. Mountain ecosystems are not too vulnerable to global climate change because only very hardy species live at high altitude.
Answer:
Warm temperatures and more frequent dry periods have stressed frog species such as the coqui making them more vulnerable to a lethal fungal infection thus reducing their populations.
Explanation:
Rise in temperature, flooding as well as drought affect biodiversity. As climate changes, there is usually an alteration of temperature as well as weather patterns, the impact is felt by
plant and animal life. According to
Scientists, there is an expectation that

what causes fast rate of growth in eichhornia
Answer:
Due to short life cycle and mode of reproduction.
Explanation:
The main cause of the fast growth rate of Eichhornia is their mode of reproduction and shorter life cycle. Eichhornia reproduce through sexually and clonally. Its life cycle is only 10 days means that within 10 days the population of Eichhornia becomes double. It reproduces through sexual reproduction as well as asexual reproduction such as clonally which also contributes for the fast growth of eichhornia plant.

Des a magnetic field flows though the inside of a magnet
Answer:
Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the magnet, toward the south pole of the magnet.
Explanation:
Answer:
However, the magnetic field lines do not just end at the tip of the magnet. They go right through it, so that inside the magnet the magnetic field points from the south pole to the north pole. Thus the magnetic field lines form a closed loop and do not have any ends.

how does shell color work to protect the egg from sunlight?
Answer:
Birds that live in cool climates lay darker eggs, as darker colors absorb more heat from the sunlight
Birds that live in hotter climates lay lighter eggs to prevent the egg from overheating.
The pigmentation acts to thermo-regulate the internal temperature of the egg, acting as a buffer between the embryo and the outside world. It does this by preventing overheating of the egg, through reflecting the sunlight off the pigmentation, rather than allowing it to be absorbed through the shell

Cheetahs have become an endangered species due to hunting and loss of their habitat. As a result, there is now very little variation in the traits within their small populations. Which of the following is a result of the limited variation in traits in today’s cheetah population compared to earlier cheetah populations that had greater variation in traits?
A. Cheetahs in current populations are more resistant to new diseases.
B. Cheetahs in current populations have better chances of survival today than they did in the past.
C. Cheetahs in current populations are less likely to become extinct.
D. Cheetahs in current populations are less likely to be able to adapt to environmental changes.
Answer:
Cheetahs in current populations are less likely to be able to adapt to environmental changes
Explanation:
i got the question wrong cuz some1 but im willing to help others this is the correct answer D is the correct answer:)
Cheetahs in current populations are less likely to be able to adapt to environmental changes. Therefore, option (D) is correct.
What is limited variation?Less possible combinations of characteristics indicates a lower level of genetic diversity within the population. Because of this, there may be fewer genetic variations available to supply potentially beneficial characteristics that can aid in the survival of the population. This can have a detrimental impact on the population's ability to adapt to changes in its environment, which can have negative effects.
Because there is less genetic variation in the current population of cheetahs, it is possible that they will have a reduced ability to adjust to changes in their environment, such as the appearance of new diseases, shifts in climate, or the loss of habitat. This might make the possibility of the population going extinct significantly more likely. Hence, the solution that you should select is option D.
