Just changed and transferred
Answer:
<u>Transient killer whales prey on marine mammals, while resident killer whales prey on Chinook salmon</u>
Explanation:
Remember, the term "ecotypes" is used to refer specifically to the observable differences found in the various kinds of whales, which includes <em>their breeding populations, their language of communication, social structure, the type of food they eat, and their hunting behavior.</em>
Thus, in the case of transient and resident killer whales in the Northeast Pacific, they are thought to represent different ecotypes rather than different species the Transient killer whales prey (feed) on marine mammals, while resident killer whales prey on Chinook salmon. Also, whales are generally thought to belong to the same species.
Answer:
The answer is <em><u>D.
</u></em>
Explanation:
Viruses can evade the processing and presentation of antigens, for example by interfering with the expression of MHC class I proteins, although this increases their susceptibility to be detected by natural killer cells (NK). However, some members of the herpesvirus, papillomavirus, retrovirus, poxvirus and flavivirus families have also developed strategies to escape the attack of NK cells and promote their survival, inhibiting cell apoptosis. Finally, some pathogens often change surface antigens frequently, as in the case of influenza viruses (orthomyxovirus).
The human immunodeficiency virus (HIV) affects CD4 + T cells and degrades the host's ability to counterattack with a strong cell-mediated immune response. There are so many tactics of immune evasion used by HIV, which have so far hindered the development of an effective vaccine.
Answer:
Due to no transfer of resistance allele.
Explanation:
The gene flow was not the cause of antibiotic resistance because the characteristics can't be transferred from one generation to the next generation. The organisms are evolved to become an antibiotic resistance due to their environmental conditions and this resistance quality is only present in the existing population and the alleles that are responsible for this resistance can't be transferred from the bacteria to the next generation so the experiment showed that gene flow was not the cause of antibiotic resistance
Warmblood mares that were pregnant (n = 10) had their peripartum alterations in blood pressure, heart rate, complete blood count, plasma electrolyte concentrations, and heart rate variability (HRV) assessed.
<h3>What is Gestation ?</h3>
The time during which an embryo, and eventually a fetus, develops inside viviparous animals is known as the gestational period. Although certain non-mammals also experience it, it is usual for mammals. When mammals are pregnant, they may have one or more gestations concurrently, as in the case of multiple births.
<h3>What is peripartum period ?</h3>
The time just prior to, during, and soon following childbirth.
Everyone agrees that the postpartum period starts when the baby is born. Although the end is less well defined, it is sometimes thought to occur six to eight weeks after delivery because by then the effects of pregnancy on many systems have essentially gone back to their pre-pregnancy states.
