Answer:
Gulpers include most rorquals, blue whales, pygmy blue whales, fin whales, Bryde's whales, humpback whales, and minke whales. Skimmers - these whales keep their mouths open most of the time, filtering food all the while. Skimmers include the right whales, pygmy right whales, and bowhead whales)

b. hemoglobin
c. fibrinogen
d. immunoglobulin
e. porphyrin
Answer: Hemoglobin
Explanation: Hemoglobin is a protein very rich in iron found in red blood cells and is responsible for the transportation of Oxygen from the lungs to the whole body. Oxygen binds to the hemoglobin in red blood cells and the red pigmentation of blood that is highly oxygenated is due to the hemoglobin content found in RBC's.
Answer:
The post-transcriptional modifications in the mRNA produced as a result of the transcription in eukaryotes provide many advantages to the mRNA.
The two post-transcriptional modifications are the addition of 7-methylguanosine cap at 5' end of mRNA called capping whereas the addition of the poly(Adenyl) tail at 3' end called tailing.
The advantages of capping are:
1. Protection of nascent mRNA from the degradation.
2. Recognition by transcription factors helps in translation.
The advantages of tailing are:
1. Protection of the mRNA from enzymatic degradation in the cytosol.
2. Transcription termination
3. Export of the mRNA from the nucleus

Explanation:
paracrine signaling
endocrine signaling
direct signaling across gap junctions
Answer:
The correct answer is the third option - endocrine signaling.
Explanation:
The endocrine signaling takes place when endocrine cell organs or glands release hormones that flow through the bloodstream and that act on distantly located target cells in the body. The endocrine system includes several glands that release or secretes different hormones.
The pituitary gland transfers signals to other endocrine glands to release or inhibit their hormone production according to the brain signals. The adrenocorticotropic hormone (ACTH) is released by the anterior pituitary gland that stimulates cortisol release in the adrenal glands in stressed conditions.
Thus, the correct answer is option third - endocrine signaling.
The pituitary gland secreting hormones is an example of endocrine signaling, where hormones are secreted directly into the bloodstream and carried to target cells.
The secretion of hormones by the pituitary gland is an example of endocrine signaling. Endocrine signaling refers to the process where glands secrete hormones directly into the bloodstream, which are then carried to the target cells elsewhere in the body. In contrast, autocrine signaling involves cells responding to their own signals, paracrine signaling refers to cells communicating with nearby cells, and direct signaling across gap junctions involves communication between adjacent cells through specific channels.

B. lichens
C the erosion of rock by weather

D.volcanic eruptions
Factors such as the decomposition of organisms and the erosion of rock by weather contribute directly to soil formation except volcanic eruptions which produce rocks.
Soil is the topmost layer of the earth on which plant grow.
Soil is important to plants as it provides the plants with the nutrients they need to grow.
Soil can either be formed directly by the breaking down of large rock particles through plant, animals and weather conditions.
The formation ofsoil involves can be due to:
Therefore, all the above factors contribute directly to soil formation except volcanic eruptions which produce rocks.
