Relative to body size, primate brain size is Group of answer choices proportional to human brain size. larger among great apes than among other primates. smaller than in other large mammals. more or less the same in large and small primates.
Larger among great apes than among other primates.
Are human brains smaller than primates?Primates are organisms that have the largest size of the brain in relation to their body ratio. Even though gorillas and orangutans are primates that are at least as big as humans, their brains are only around one-third the size of humans'. This difference has been cited as proof that the human brain is around three times larger than what would be expected for a monkey species with a body similar to that of a human.
Primates, including humans, have by far the largest brains of any terrestrial mammal when compared their size. The neocortex, which accounts for more than 80% of the mass of the human brain, is where the enlargement is nearly entirely concentrated.

How much time does it take for a 1-solar-mass protostar to reach the main sequence?
a. 10–100 million years
b. less than 10,000 years
c. 100,000 to 1 million years
d. 1–10 billion years
a. 10–100 million years is the answer.
Solar mass stars are thought to accrete rapidly. Premain sequence solar mass protostars are probably formed by the collapse of part of a molecular cloud into the "cloud core" in about 105 years (Hartmann, 2000). Strong outflows and jets are sometimes observed.
Star formation begins with the collapse of molecular clouds and fragmentation into highly dense masses. These masses initially contain about 0.01 solar masses, but increase in mass as the surrounding matter is collected by accretion.
Protostars are very young stars, still collecting mass from their original molecular clouds. The protostar stage is the earliest in the process of stellar evolution.

What cytoskeletal elements support the flagellum, and what is its function?
Cytoskeletal filaments provide the basis for cell movement. For instance, cilia and (eukaryotic) flagella move as a result of microtubules sliding along each other. In fact, cross sections of these tail-like cellular extensions show organized arrays of microtubules.
The cytoskeleton of eukaryotic cells is made of filamentous proteins, and it provides mechanical support to the cell and its cytoplasmic constituents. All cytoskeletons consist of three major classes of elements that differ in size and in protein composition.
Microtubules are the largest type of filament, with a diameter of about 25 nanometers (nm), and they are composed of a protein called tubulin. Actin filaments are the smallest type, with a diameter of only about 6 nm, and they are made of a protein called actin. Intermediate filaments, as their name suggests, are mid-sized, with a diameter of about 10 nm. Unlike actin filaments and microtubules, intermediate filaments are constructed from a number of different subunit proteins.
The cytoskeleton is a structure that helps cells maintain their shape and internal organization, and it also provides mechanical support that enables cells to carry out essential functions like division and movement.

Yes. True vertebrates have a true head that develops from a neural crest of cells and hard structures surrounding the notochord.
The neural crest, which forms early in the development process in vertebrate embryos, is a fold on the neural plate where the neural and epidermal ectoderms converge. As an embryo grows, the neural crest produces neural crest cells (NCCs), which can differentiate into a variety of different cell types and contribute to tissues and organs.
The notochord is a temporary structure that plays a crucial role in higher animals. It secretes substances that communicate with all neighbouring tissues, telling them where they are and what will happen to them.

Answer:
Phototropism is the growth of an organism in response to a light stimulus. Phototropism is most often observed in plants, but can also occur in other organisms such as fungi. The cells on the plant that are farthest from the light contain a hormone called auxin that reacts when phototropism occurs.

What is the most likely effect of a mutation that changes the repeat sequence found in terc from 3’-cccaau-5’ to 3’-ucaggacg-5’?.
If the repeat sequence of telomere changes from 3’-cccaau-5’ to 3’-ucaggacg-5’ due to any mutation in TERC gene then the telomerase enzyme will be unable to attach to the 3' overhung of the telomere sequence and cannot elongate new DNA strand [telomeric part]. As a result, the telomeres of chromosomes cannot be elongated and the entire chromosome or the cell will be lost after a few rounds of division.
Telomere: They are short repeating sequences found at the end of the chromosome whose function is to save the chromosomes from degradation. But after each round of replication, the length of the telomeres becomes shorter than the previous and after a certain number of cell divisions, the telomeres become so short that they trigger the cell to stop dividing or to self-destruct (undergo apoptosis).
So, to prevent the shortening of telomeres, the TERC gene codes a telomerase enzyme which is a type of reverse transcriptase made up of two components: an RNA part that is complementary to the repeated telomeric sequence and a protein part that can add the nucleotides to the 3' end of the telomere.
After every cell division, the telomerase enzyme gets attached to the 3' end of the shortened telomere end and synthesizes the complementary DNA to the RNA part of the enzyme until the length of the telomere is restored again.

Here, given-
homozygous alleles 'a' have a frequency of 0.3.
Also the alleles are in equilibrium in a Hardy-Weinberg population. The frequency of individuals that are homozygous for this allele are= 0.49.
The Hardy-Weinberg equilibrium can be defined as the principle which states that the variation in the genetic makeup of a population remains constant and unchanged till there are no external interferences, influencing the population.
Calculation-
[tex]p + q= 1\\0.3 + q= 1\\q= 1- 0.3\\q= 0.7\\[/tex]
Then to find the frequency of the individuals homozygous for this allele the following formula needs to be used-
[tex]p^{2} + 2pq + q^{2} = 1\\Here,\\p^{2}= dominant homozygous frequency\\2pq= heterozygous frequency\\q^{2}= recessive homozygous frequency\\[/tex]

Tumor cells have experienced a variety of genetic and epigenetic changes as compared to normal cells. Because these alterations frequently underpin cancer genesis, progression, and therapy resistance, the efficacy of model systems is dependent on their capacity to replicate the genetic abnormalities seen in original tumors.
Tumor-derived cell lines have long been utilized to explore the underlying biologic processes in cancer, as well as as screening platforms for identifying and assessing anticancer treatment effectiveness.
Following advancements in high-throughput technology and multigroup collaborative efforts, several -omic measurements across over a thousand cancer cell lines have been produced.
