Mesopotamians gave offerings and animal sacrifices to the gods so that *
the gods would not steal their animals
they could get rid of their surplus of food
the gods would beat their enemies
the gods would influence nature to help them
Answer:
the gods would influence nature to help them
Explanation:
The animal sacrifices were made to the gods so that the gods would influence nature to help them. They believed that when things were going bad for them such as crops not growing, or rain not falling for an extended period of time, it meant that the gods were angry. In order to please them, the Mesopotamians would sacrifice an animal in the name of their gods to please them. They believed if the gods were happy they would influence nature to help produce food in their lands so that they can harvest and survive.

When your muscles contract to move your body, such as during walking, work is done, and work requires energy. Based on the law of conservation of energy, from where does this energy come?.
The energy for muscle contraction comes from the metabolism of food.
What does the law of conservation of energy say?The law of conservation of energy tells us that energy can not be created or destroyed, is transformed. Applying this law for the muscle contraction, this energy cannot come from nothing. Then the energy generated from food (glucose, fatty acids, proteins) will be transported, mainly glucose, to the muscle cell and will be transformed into a metabolite for the use of this energy in muscle contraction.
Thanks to this metabolite, ATP, the muscle is able to contract and give way to the displacement of myofilaments. Apart from providing energy, ATP will also be a regulator of the contraction process together with other elements such as calcium and magnesium, thus demonstrating the importance of the presence of energy.
Therefore, we can confirm that the energy for muscle contraction comes from the metabolism of food.

Screen Why is it important to administer an antiviral agent to an infected person within 48 hours of the appearance of symptoms? The H1N1 virus is transmitted through a vector host, such as a mosquito. The H1N1 virus is dormant in cells. The H1N1 virus does not mutate. The H1N1 virus replicates quickly.
Answer:
The H1N1 virus replicates quickly.
Explanation:
The H1N1 virus replicates quickly, which is why it is of high importance that an antiviral agent is administrated within the first 48 hours so that the reproduction rate of the virus can be lowered, resulting in an effective treatment against H1N1 flu. In other words, by administrating an antiviral in the first 48 hours, we are helping the body to fight the virus since the antiviral stops the reproduction of it, and we increase the chances of succeeding at it.
cleavage stimulating factor 64 depletion mitigates cardiac fibrosis through alternative polyadenylation pdf
The discussion of cleavage stimulating factor 64 depletion mitigates cardiac fibrosis through alternative polyadenylation is given in below paragraph-
By cleaving the poly(A) sequence and adding it at various polyadenylation sites (PAS) in the 3′UTR, alternative polyadenylation (APA) controls the expression of genes and creates transcript isoforms of various lengths. Cleavage Stimulating Factor 64 (CstF64) is an APA regulator that affects PAS choice and controls 3′UTR length. The 3′UTR is shortened as a result of CstF64's preference for the usage of proximal PAS, which improves the stability of the target genes while also improving protein expression. The purpose of this study is to look at the involvement of CstF64 in cardiac fibrosis, a significant occurrence that results in heart failure. By measuring distal PAS (dPAS) utilization in left ventricular (LV) tissues and cardiac fibroblasts from HF, we were able to assess the expression of CstF64, essential profibrotic genes, and their 3′UTR alterations.
By measuring the distal PAS (dPAS) utilization in cardiac fibroblasts and left ventricular (LV) tissues from HF patients, we were able to assess the expression of CstF64, important profibrotic genes, and their 3′UTR alterations. In addition to enhanced fibrosis gene expression, such as COL1A and FN1, and considerable 3′UTR shortening, CstF64 was elevated in HF LV tissues and cardiac fibroblasts. Additionally, HF cardiac fibroblasts displayed elevated TGF-R1 expression, which is associated with a notable reduction in TGF-R1 length. Our research reveals that CstF64 plays a significant role in myofibroblast activation and the promotion of cardiac fibrosis during HF via APA. Therefore, restricting RNA processing by CstF64-mediated approaches in human HF may offer a new therapeutic treatment approach.
What is cardiac fibrosis?Cardiac fibrosis often refers to an excessive buildup of extracellular matrix in the cardiac muscle, but the word may also refer to an aberrant thickening of the heart valves brought on by unsuitable cardiac fibroblast growth. As heart failure progresses, fibrotic cardiac muscle becomes stiffer and less flexible. Although a specific process of valvular pathology is highlighted in the explanation that follows, there are additional causes of valve pathology and cardiac muscle fibrosis.

one molecule of dietary glucose can be oxidized through glycolysis and the citric acid cycle to generate a maximum of 32 molecules of atp. calculate the fraction of this energy that is lost when the glucose is stored as glycogen before it is catabolized.
One molecule of dietary glucose is oxidized through glycolysis and the citric acid cycle in order to generate a maximum of 32 molecules of ATP. Then 2/32 of this energy is lost when the glucose is stored as glycogen before it is catabolized.
If a dietary glucose is provided directly into the glycolysis pathways, a total of 32 molecules of the Adenosine triphosphate (ATP) are produced per molecule of glucose. Glycolysis provides a total production of 2 ATP per molecule of glucose.
Although the citric acid cycle (CAC) produces an additional 2 ATP per molecule of glucose. Oxidative Phosphorylation provide total of 28 ATP from the products of glucose catabolism. So, 32 molecules of ATP are produced in this way. A cell could even store dietary glucose for later use, in the form of glycogen.
However, In this pathway, 1 ATP is consumed to produce G1P (glucose-1-phosphate), and then it reacts with UTP (uridine triphosphate) to produce a UDP-glucose (uridine-diphospho-glucose). This step indirectly consumes ATP in form of a UTP substrate. 2 molecules of ATP consumed per molecule of glucose added to a glycogen polymer.
Therefore, If two molecules of ATP are consumed for storing glucose as glycogen. So, 6.25% or 2/32 of the energy stored as glucose is lost when it is stored as a glycogen.

cogoli a, mitogenic signal transduction in t lymphocytes in microgravity. j leukoc biol 1993, 53(5):569-575.
The activation by concanavalin A Con A of human peripheral blood lymphocytes (PBLs) in the presence of monocytes as accessory cells were once investigated in cultures uncovered to microgravity prerequisites in Spacelab. Activation of T cells used to be measured as the incorporation of [3H]thymidine into DNA, secretion of interleukin-2 (IL-2), interferon-gamma, and expression of IL-2 receptors. Whereas, as observed in earlier experiments, the activation of resuspended T cells is strongly inhibited, activation of cells attached to microcarrier beads is greater than doubled in microgravity. The results suggest that the depression of the activation in resuspended cells may also be attributed to a malfunction of monocytes performing as accessory cells. Though the ultrastructure of resuspended monocytes is now not altered in microgravity, the secretion of IL-1 is strongly inhibited. Our data propose that (1) IL-2 is produced independently of IL-1, (2) IL-1 production is brought about only when monocytes (and lymphocytes?) adhere to microcarriers, (3) the expression of IL-2 receptors depends on IL-1, and (4) furnished enough IL-1 is available, activation is better in microgravity. Finally, cultures of resuspended PBLs and monocytes in microgravity represent a whole and natural gadget in which monocytes are now not operational. This can also be beneficial for research of the position of accent cells and cell-cell interactions in T lymphocyte activation.
