A number of systems for pumping ions across membranes are powered by atp. such atp-powered pumps are often called atpases, although they do not often hydrolyze atp unless they are simultaneously transporting ions. because small increases in calcium ions in the cytosol can trigger a number of different intracellular reactions, cells keep the cytosolic calcium concentration quite low under normal conditions, using atp-powered calcium pumps. for example, muscle cells transport calcium from the cytosol into the membranous system called the sarcoplasmic reticulum (sr). if a resting muscle cell's cytosol has a free calcium ion concentration of 10-7 while the concentration in the sr is 10-2, then how is the atpase acting?

two haploid daughter cells
four diploid daughter cells

Answers

I think two haploid daughter cells

Answer: Option B

Explanation:

In some species there is a very small interphase, or interkinesis before the cell enters in the the process of meiosis II.

The two daughter cells that are produced after meiosis I go though the process of meiosis II. During the process of meiosis II the two sister chromatids which lies in daughter cells separate, resulting in formation of four haploid daughter cells. This process is similar to mitosis.

Purple loosestrife is an invasive plant that was brought to the United States in the 1800s. Which of the following describes the most likely long-term consequence of the introduction of purple loosestrife?

A. Herbivores will overpopulate due to an abundant food source.
B. Native plant populations will decrease as they are choked out by the purple loosestrife.
C. Purple loosestrife will begin to crossbreed with native plant species.
D. Air quality will improve as a result of the increased rate of photosynthesis.

Answers

The best answer is B) Native plant populations will decrease as they are choked out by the purple loosestrife.

Two results are likely when an invasive species, plant or animal, is introduced to a new population: that species will compete very well in the new environment or will not be successful. 

One possible result of the introduction of the purple looseleaf is that the species will do very will in its new environment, out-competing native plant species and thus choking them out of their natural environment.

Answers

Final answer:

The lipid and protein compositions of membranes in organelles within the endomembrane system are determined by the specific functions of each organelle. Each organelle requires a unique lipid and protein composition to support its function.

Explanation:

The differences in the lipid and protein compositions of the membranes in various organelles in the endomembrane system are largely established by the specific functions and roles of each organelle. Each organelle has unique requirements for lipid and protein composition to support its function. For example, the endoplasmic reticulum (ER) is responsible for lipid synthesis, so it has a higher concentration of lipids compared to other organelles. The Golgi apparatus, on the other hand, is involved in protein modification and sorting, so it has a higher concentration of specific proteins.

Answers

Final answer:

A liger, as the hybrid offspring of a male lion and a female tiger, is sterile, exemplifying a biological phenomenon where the mixed chromosomes from parents of two different species produce non-viable gametes.

Explanation:

The offspring of a male lion and a female tiger, known as a liger, exemplifies a phenomenon of hybrid sterility. Male ligers are unable to produce offspring. This is due to the fact that the parental species, lions and tigers, have a different number of chromosomes which, when combined, create a mismatched set. Although the ligers and tigons have a functional set of genes, the gametes produced during meiosis do not have a complete set of genes necessary for survival in subsequent generations. This biological concept is seen in other animal hybrids as well, such as mules and hennies, which are the sterile offspring of horses and donkeys. Understanding these hybridization outcomes is vital for conservation and biology.

Various enzymes function most efficiently under different sets of “optimal” conditions. explain why this is the case.

Answers

An enzyme is protein and it needs to maintain its 3D structure as the enzyme work like "lock and key". A little deformation to the enzyme structure can disable its functions.
Protein is prone to denaturation. Condition like pH and temperature can affect the protein and cause an alteration to its structure. Higher temperature should speed up the reaction but too high temperature might damage the enzyme. So, the "optimal" condition would be the condition where the enzyme structure is not altered.

Enzymes work efficiently under specific conditions due to their adaptation to different cellular environments and factors like pH and temperature. Variations in enzyme activity depend on environmental factors and substrate concentration. These factors ensure optimal biochemical reactions in cells.

Enzymes are biological catalysts that function most efficiently under specific optimal conditions. Several factors contribute to this phenomenon:

Enzymes are adapted to their cellular environments, so different cells have varying enzyme needs. For example, stomach cells require different enzymes compared to fat storage cells or nerve cells.Environmental factors like pH, temperature, and salt concentration significantly impact enzyme activity. For instance, human pathogens have enzymes that work best at 37°C, while microbes in hot springs have enzymes optimized for high temperatures.The presence of dietary intake influences enzyme activity in digestive organs, where more enzymes are needed to process nutrients after a meal.Enzyme activity is also influenced by substrate concentration. Increased substrate levels enhance enzyme activity up to a saturation point.

These conditions ensure that enzymes efficiently catalyze reactions necessary for cellular functions to adapt to their varying environmental and physiological requirements.

Which mechanism describes the formation of multinucleated skeletal muscle fibers?

Answers

Multi nucleated skeletal fibers are formed by the FUSION OF MONO NUCLEATED MYOBLASTS.
The myoblast are made up of only one nucleus in their cells, that is why they are described as mono nucleated. When mono nucleated cells fuse together they form multi nucleated fibers which is ribbon like in shape. 
Final answer:

Multinucleated skeletal muscle fibers are formed by the fusion of embryonic myoblasts, each contributing its nucleus to the mature muscle fiber, resulting in a cell with many nuclei. This aids in the production of the large amounts of proteins necessary for muscle function. Cardiac and smooth muscle cells do not become multinucleated because the myoblasts do not fuse.

Explanation:

The formation of multinucleated skeletal muscle fibers is described by the mechanism in which myoblasts, which are embryonic muscle-forming stem cells, fuse together. Early in development, embryonic myoblasts, each with its own nucleus, merge to form mature muscle fibers. This process ensures that each nucleus from the contributing myoblasts is preserved within the mature muscle fiber, giving rise to a muscle cell with many nuclei or a multinucleated structure. Since skeletal muscle fibers require the manufacture of significant amounts of proteins and enzymes for muscle contraction, having multiple nuclei allows for the production of large quantities of these molecules. Unlike skeletal muscle, cardiac and smooth muscles are not multinucleated because myoblasts do not undergo fusion during their formation.
