Answer:
Hydrogen ion(H+)
Explanation
The human blood has carbonic acid and bicarbonate anion as buffer to maintain the blood pH between 7.35 and 7.45. A virtual value higher than 7.8 and 6.8 can lead to death.
Taking coffee which has a low pH will lower the pH of the blood. In order to raise the pH back to normal and lower the level of acid present in the system. The human buffering system will to take up Hydrogen ion.

Explanation:
Sexual reproduction is the kind of reproduction that requires two organisms (male and female) to form an offspring. The male organism produces gametes called SPERM while the female organism produces gametes called EGG. These two gametes come together in a process called FERTILIZATION to produce a zygote, which develops into an offspring.
In sexual reproduction, gametes are produced by organisms involved via a process called MEIOSIS. Meiosis, however, reduces the chromosome number of the gametes by half. However, one process unique to only meiosis and sexual reproduction is called CROSSING OVER.
Crossing over is the process whereby chromosome segments is exchanged between non-sister chromatids of homologous chromosome. This process causes a recombination of chromosomes (alleles) in such a way that the gametes will be genetically different from the parent organisms (genetic variation). According to this question, sexual reproduction leads to more genetic variation than asexual reproduction due to the process of CROSSING OVER that occurs in sexual reproduction.
Answer: a. Measuring the amount of rain that falls in a 24-hour period in a rain gauge.
I originally asked for the images but I will give it my best shot at answering your question without them! :D
There are only three types of plant tissues:
1. Dermal
2. Ground
3. Vascular
The dermal tissue is the outside of the plant's root, stem, or leaf, A.K.A the the skin. If you're looking at a circular image, what ever is pointing to the outside ring of the stem is the dermal tissue.
The ground tissue is the flesh of the plant that is inside the dermal tissue. It surrounds the vascular tissue in the middle of the stem. Whatever letter is pointing to the wide, fleshy ring, that is touching the dermal tissue is the ground tissue. It is the largest part of a plants stem, roots, or leaves.
Lastly, the very inner ring or rings of the plant is the vascular tissue. It's made up of xylem and phloem. This can be found in many different places depending on the part of the plant, but what you're looking for is tiny circles within the ground tissue. If you're looking at the roots, you will see one circle in the very center of the plant, surrounded by ground tissue. If you're looking at the leaves, you will see one circle as well, and additionally other tiny circles throughout the ground tissue in each wing. Lastly, if you're looking at the stem, you'll see a circle of tiny circles within the ground tissue. These small circles are all vascular tissue.
Answer:
Hello! There are numerous things that support Darwin's theory of evolution, but the most credible ones include:
*Homologous structures - structures that are similar in structure but different in function (e.g. wing of a bat and arm of a human).
*Embryology - the study of embryos
*Continental drift - some fossils of organisms that were adapted to a different environment are often found in different climates/areas they don't seem to have been adapted to.
*DNA - similarities in the genomes of certain animals are often used to compare amino acid sequences and protein production.
I hope I helped!
There are a bunch more, but I decided to leave a select few for you to write about.
