Myxedematous coma
Explanation;Myxedema coma is a severe hypothyroidism leading to decreased mental status, hypothermia, and other symptoms related to slowing of function in multiple organs.it is a loss of brain function as a result of severe, longstanding low level of thyroid hormone in the blood.It is a rare life threatening complication of hypothyroidism.5. Suppose that a dominant allele (P) codes for a polka-dot tail and a recessive allele (p) codes for a solid colored tail. In addition, suppose that a dominant allele (L) codes for long eyelashes and a recessive allele (l) codes for short eyelashes. If two individuals heterozygous for both traits (tail color and eyelash length) mate, what's the probability of the phenotypic combinations of the offspring?
A. 1:1 ratio (half are polka-dot tails and short eyelashes; half are solid tails and long eyelashes)
B. 1:1 ratio (half are polka-dot tails and long eyelashes; half are solid tails and short eyelashes)
C. 9:3:3:1 ratio (9 polka-dot tails and long eyelashes, 3 polka-dot tails and short eyelashes, 3 solid tails and long eyelashes, 1 solid tail and short eyelash)
D. 9:3:3:1 ratio (9 polka-dot tails and short eyelashes, 3 polka-dot tails and long eyelashes, 3 solid tails and short eyelashes, 1 solid tail and long eyelash)
Answer:
C.
Explanation:
According to your problem, you have to two traits to be crossed, tail and eyelashes:
P - polka-dot tail L - long eyelashes
p - solid colored tail l - short eyelashes
It says we cross two individuals that are HETEROzygous for both traits, this means that their genotypes have each allele for each trait. So the cross would be:
PpLl x PpLl
Attached is a Punnet for this cross and ratio count for both genotype and phenotype.
The ratio based on phenotype would be the following:
9 polka-long: 3 polka-short: 3 solid-long: 1 solid-short

Which statement most accurately describes what happens to proteins that lack an ER signal sequence?
They are inserted into the ER membrane but do not enter the ER lumen.
They are inserted into the plasma membrane.
They bypass the ER but enter the Golgi apparatus.
They are released into the cytosol.
The correct answer is: They are released into the cytosol.
A a sequence consisting of 5-30 hydrophobic amino acids on the N-terminus, which is called signal peptide or signal sequence is responsible for directing the transport of the synthesized protein. Proteins that contain such sequence are destined for secretion form the cell (vesicular), for the plasma membrane, the lumen or membrane of either the (ER), Golgi or endosomes. So, when the protein lack the sequence, it is released in the cytosol.
The process of photosynthesis can be generally expressed by: carbon dioxide + water glucose + oxygen The process of cellular respiration can be generally expressed by: glucose + oxygen carbon dioxide + water What can be said about these two reactions?
Photosynthesis and cellular respiration are reciprocal processes where the byproduct of one process is the necessary component for the other. Both processes utilize electron transport chains to transfer energy and occur in chloroplasts and mitochondria respectively.
Explanation:The processes of photosynthesis and cellular respiration can essentially be viewed as reciprocal. In photosynthesis, light energy is absorbed to create glucose and oxygen from carbon dioxide and water. This process occurs in chloroplasts. Conversely in cellular respiration glucose and oxygen are metabolized to produce energy, with carbon dioxide and water as byproducts. This process occurs in the cytoplasm and mitochondria. The byproducts of each process become the necessary components for the other process, thus forming an efficient biological cycle. Both processes rely on electron transport chains to capture and transfer the necessary energy for these processes.

How many copies of DNA does meiosis start with?
Final answer:
Meiosis starts with one diploid cell which has duplicated its DNA, creating two sets of each chromosome. It undergoes two rounds of cell divisions to produce four unique haploid gametes, each with half the original DNA content.
Explanation:
Meiosis begins with one diploid cell that contains two copies of each chromosome, one from each parent. After DNA replication occurs in the S phase of the cell cycle, meiosis proceeds through two cell divisions. The first division, meiosis I, separates homologous chromosomes, each made of two sister chromatids, into two daughter cells. These cells contain a mix of maternal and paternal chromosomes due to random assortment and the crossing over.
During the second meiotic division, or meiosis II, the sister chromatids are separated into four genetically unique haploid cells, each with half the DNA content of the original diploid cell. In humans with 46 chromosomes (23 pairs), the resulting cells from meiosis, which become gametes, each have 23 chromosomes. These are gametes such as sperm in males and oocytes in females.
The variability of the resulting gametes is vast, with the possibility of over eight million (223) different combinations from chromosome alignment alone, excluding additional genetic variation introduced by crossover.
Albino trees exist in nature, but they're rare. These trees contain a gene mutation that causes them to lack chlorophyll, so their leaves are white. In California, albino redwood trees are parasites. They survive off the energy from nearby redwood trees. Why do you think they need to use energy from other trees to survive?
Answer:Trees need chlorophyll to make energy. Because albino trees don’t have chlorophyll, they can’t create their own energy. So, they must take energy from other trees to survive.

How is it possible for one of the species in a mimicry relationship not to be aware of the other?
How do population cycles impact trophic levels?
Final answer:
In a mimicry relationship, one species can mimic another without direct contact, influenced by predator selection pressures. Population cycles influence trophic levels, causing fluctuations throughout the ecosystem. These interactions can drive evolutionary changes and affect community dynamics.
Explanation:
In a mimicry relationship, it's possible for one species to be unaware of the other because mimicry involves one species evolving to share similar traits with another without direct interaction; this often occurs due to selective pressures from predators. For instance, if a harmless species resembles a poisonous one, predators might avoid it even if the two species never meet.
Population cycles impact trophic levels significantly. As the population of prey fluctuates, predator numbers also change in response due to availability of food. This can lead to cyclical patterns of abundance and scarcity that ripple through the trophic levels, influencing the entire ecosystem. Predators and prey can also drive each other's evolution through natural selection, each adapting to improve survival chances against the other.
Interspecific competition occurs when different species compete for the same resources, potentially leading to the exclusion or decline of one species, or to evolutionary changes such as niche differentiation. All these interactions can deeply affect the evolution of the species involved, shaping the structure and dynamics of communities and ecosystems.
To what part of the cell do the products of transcription travel
Cytoplasm would be the answer.
The products of transcription, which are mRNA molecules, travel from the nucleus to the cytoplasm of the cell. Here they are translated by ribosomes into proteins. The transportation of mRNA is a key aspect of the central Dogma of Life, covering the flow of genetic information within a biological system.
Explanation:The products of transcription, which are mRNA molecules, travel to the cytoplasm of the cell. In the nucleus, the DNA is transcribed into RNA. Afterwards, the newly synthesized RNA, serving as the intermediate messenger, is transported out of the nucleus and into the cytoplasm where ribosomes translate the RNA into protein. This separation of transcription occurring only within the nucleus, and translation only outside the nucleus in the cytoplasm, is particular to eukaryotic cells.
The transcription process involves the DNA double helix partially unwinding in the region of mRNA synthesis, forming a transcription bubble. It's crucial to note that the mRNA product is complementary to the DNA template strand and that in mRNA, T nucleotides are replaced with U nucleotides.

Cholesterol serves several essential functions in mammalian cells. Which of the following is not influenced by cholesterol?
Select one:
a. membrane permeability
b. membrane fluidity
c. membrane rigidity
d. membrane thickness
The correct answer is: d. membrane thickness
Cholesterol is the second major lipid in the structure of the cell membrane (phospholipids are the major lipid components).
Cholesterol is rigid, so it gives the cell membrane extra support (strength and hardness) by immobilizing some of the lipid molecules around them. This rigidity makes it harder for small molecules to pass through the membrane, so it also has the influence on cell membrane’s permeability (the membrane becomes effective barrier to ions).
Cell membrane’s fluidity is also under the influence of the cholesterol which helps generate some extra space between the lipids allowing them to move freely throughout the membrane.
