Answer:
A. Where does sugar enter the blood?
After eating food, in the intestine the glucosa is absorbed by an SGLT1 cotransporter who releases it to the bloodstream.
B. How can you tell where sugar enters the blood?
Making an analysis of its high concentration in the epithelial cells of the intestine
C. Where is sugar removed from the blood?
After traveling through the blood flow, the sugar enters the cells of the body that require it, for example, muscle cells. Excess glucose in the blood is removed by the kidney through urine.
D. How can you tell?
The filtration of glucose by the kidneys can be verified by an analysis of their co-concentrations in these renal cells and Medical tests of the urine sample.
Answer:
An angiosperm seed contains structures contributed by three generations of plants.
Explanation:
The spermatophytes, also known as phanerogams, represent a group of seeded plants that have developed special structures for reproduction. This group (spermatophytes) consists of gymnosperms or 'naked seeds', and angiosperms or 'enclosed seeds'. The seed is an organ generated from the ovule after fertilization by the pollen grain, which gives rise to a seedling during the process of germination. In flowering plants, seeds are generated by a process of double fertilization and consist of three tissues: 1-an embryo (generally diploid) formed by repeated mitotic division of the zygote cell, 2- an endosperm tissue (generally triploid, 3n) that nourishes the embryo during its growth, and 3-a seed coat generated from the integuments of the ovule. In angiosperms, seeds consist of three generations: the gametophyte that provides nutrients to the embryo, the embryo, and the seed coat which is generated from the parental tissue (sporophyte).
Answer: protons
Explanation:
Changing the number of protons would change it into an atom of a different element.
Here is your answer:
Temperature, sunlight, and water are examples of "abiotic factors'' or the second option. Abotic factor's are non-livings things that would affect organisms. For example temperature is non-living but can affect organisms, the same for sunlight, and water. It's not the first option because mineral sources are like mining shafts and others like coal. It's not biotic factors are all living things and temperature, sunlight, and water are non-living. Also food sources are food, for example gardens, and plantations etc...
Hope this helps!
