which of the following is not described in the lecture presentation as a definitive characteristics of organisms, separating them from non-living things?
"They have mass and take up room" is not described in the lecture presentation as a definitive characteristics of organisms, separating them from non-living things.
Numerous essential traits or capabilities are shared by all living things:
1) Order: Cells make up organisms, which are highly coordinated, ordered structures. Even very basic, single-celled creatures are astonishingly complicated because within each cell, atoms form molecules, which in turn form cell organelles and other cellular inclusions.
2) Reproduction: DNA replication is the first step in the reproduction of single-celled organisms. Then, as the cell is about to split into two new cells, they equally divide it. Specialized reproductive germline cells that develop into new individuals are frequently produced by multicellular organisms. DNA-containing genes are transferred to the progeny of an organism during reproduction. The presence of these genes guarantees that the progeny will be of the same species and will share traits like size and shape.
3) Expansion and development: Each organism's growth and development are governed by particular instructions encoded in its genes. A species' offspring will develop into adults who share many traits with their parents thanks to the instructions provided by these genes, which control cellular growth and development.
4) Energy conversion: For their metabolic processes, all living things need an energy source. Others use the chemical energy found in the molecules they consume as food. Some species use the chemical energy found in food molecules.

You have prepared lipid vesicles (spherical lipid bilayers) that contain Na+-K+ pumps as the sole membrane protein. Assume for the sake of simplicity that each pump transports one Na+ one way and one K+ the other way in each pumping cycle, as illustrated. All of the Na+-K+ pumps are oriented so that the portion of the molecule that normally faces the cytosol faces the outside of the vesicle. Predict what would happen under each of the following conditions.
A. The solution inside and outside the vesicles contains both Na+ and K+ ions, but no ATP.
B. The solution inside the vesicles contains both Na+ and K+ ions; the solution outside contains bothions, as well as ATP.
C. The solution inside contains Na+; the solution outside contains Na+ and ATP.
D. The solution is as in B, but the Na+-K+ pump molecules are randomly oriented, some facing one direction, some the othe
A. If the solution inside and outside the vesicles contains both Na+ and K+ ions, but no ATP, the pumps will not work as ATP is required for their functioning.
The vesicles will remain in a state of equilibrium, with no movement of ions across the lipid bilayer.
B. If the solution inside the vesicles contains both Na+ and K+ ions and the solution outside contains both ions and ATP, the pumps will use ATP to actively transport Na+ ions out of the vesicles and K+ ions into the vesicles. This will result in a concentration gradient, leading to an exchange of ions across the lipid bilayer.
C. If the solution inside the vesicles contains Na+ and the solution outside contains Na+ and ATP, the pumps will use ATP to pump Na+ ions out of the vesicles. This will result in a concentration gradient of Na+ ions across the lipid bilayer, leading to the diffusion of Na+ ions from outside to inside the vesicles.
D. If the solution is as in B, but the Na+-K+ pump molecules are randomly oriented, some facing one direction and some the other, the pumps will not function efficiently. The random orientation of the pumps will result in some pumps working to pump Na+ out and K+ in, while others will pump Na+ in and K+ out, leading to a chaotic exchange of ions across the lipid bilayer.

which statement is accurate regarding the effects of parathyroid hormone on bones for the maintenance of calcium balance? increases bicarbonate and sodium excretion
Parathyroid hormone PTH works to maintain calcium balance by affecting multiple systems in the body, including bones, kidneys, and the intestines.
Regarding the effects of Parathyroid hormone PTH on bones, PTH increases the mobilization of calcium from bones into the bloodstream. This helps to raise low blood calcium levels and maintain calcium balance in the body. PTH stimulates the activity of osteoclasts, which are cells responsible for breaking down bone tissue and releasing calcium into the bloodstream.
However, excessive and prolonged PTH secretion can lead to negative effects on bones, such as decreased bone density and increased risk of osteoporosis. This is why maintaining normal PTH levels is important for optimal bone health.
PTH also affects renal (kidney) function and can increase bicarbonate and sodium excretion. This can help to regulate the acid-base balance in the body and maintain normal blood pH levels.
In conclusion, PTH plays a crucial role in maintaining calcium balance in the body by affecting bones, kidneys, and the intestines. However, it is important to maintain normal PTH levels to avoid negative effects on bone health.

A woman's uterus experiences pregnancy while one or more gestations grow there (womb). More than one child, such as twins, is born during a multiple pregnancy. While assisted reproductive technology methods can also result in pregnancy, sexual activity is typically the way that it happens. Any number of outcomes are possible for pregnancies, including live delivery, miscarriage, forced abortion, and stillbirth. The gestational age, or time since the start of the last menstrual period (LMP), is the normal time frame for childbirth, which typically happens approximately 40 weeks after the LMP. There are little over nine months left. The length is roughly 38 weeks if measured in terms of fertilisation age. According to the definition of pregnancy, which is defined as "the presence of an implanted human embryo or foetus in the uterus," implantation takes place 8–9 days following fertilisation.

Option D. Inheritance alone may not account for thick leg muscles in dogs.
The conclusion that inheritance alone may not account for thick leg muscles in dogs is based on the data collected, which showed that dogs that lived outdoors had thicker leg muscles than dogs that lived indoors. This suggests that environmental factors, such as exercise, may also play a role in determining the thickness of leg muscles in dogs. It is possible that both genetic and environmental factors interact to determine the thickness of leg muscles in dogs, and that inheritance alone is not sufficient to explain the observed differences.
