Nerves - transmit impulse of sensation to brain or spinal cord, then to muscles and organs
Answer:
The correct answer is - they both have highly folded membranes.
Explanation:
Organelles such as the endoplasmic reticulum, Golgi apparatus, and mitochondria have highly folded double membranes. This highly folded membrane provides the increased surface area in the organelle.
As the inner membrane of these organelles is the site for many chemical reactions the highly folded or layered membranes get more space for such reactions to occur due to increased surface area.
Answer;
Mendel's work was not well known until many years after Darwin published his theory of evolution
Explanation;
-Mendel's work was ignored because it was not widely distributed, and he didn't make an effort to promote himself. In actual fact, the reasons are more complex.
-Gregor Mendel had the answer to Darwin's problem. Traits were not blended, but inherited whole. And according to Mendel's laws of inheritance, a trait that might disappear in one generation might reappear in the following generation. Modern Neo-Darwinism combines both Darwin's and Mendel's work.
Answer:
The oxygenated blood enters into the heart by pulmonary veins into the left auricle, then the left ventricle. Then this RBC enters the aortic valve and moves upward.
It enters the aorta and from the aorta to aortic vessels. From aortic vessels, the blood goes to descending aorta. This supplies RBC to different tissue parts.
From descending aorta the blood flows to iliac arteries which are further branched into several arteries, which supply blood to lower part of the body i.e. legs, pelvis.
The subclavian artery provides blood to hands and shoulders, hands. Left and right carotid arteries supply blood to the brain from the heart.
Answer:
True
Explanation:
A mutation is any alteration in the genetic sequence of the genome of a particular organism. Mutations in the germline (i.e., gametes) can pass to the next generation, thereby these mutations can increase their frequency in the population if they are beneficial or 'adaptive' for the organism in the environment in which the organism lives (in this case, an insect/bug). The mutation rate can be defined as the probability of mutations in a single gene/<em>locus</em>/organism over time. Mutation rates are highly variable and they depend on the organism/cell that suffers the mutation (e.g., prokaryotic cells are more prone to suffer mutations compared to eukaryotic cells), type of mutations (e.g., point mutations, fragment deletions, etc), type of genetic sequence (e.g., mitochondrial DNA sequences are more prone to suffer mutations compared to nuclear DNA), type of cell (multicellular organisms), stage of development, etc. Thus, the mutation rate is the frequency by which a genetic sequence changes from the wild-type to a 'mutant' variant, which is often indicated as the number of mutations <em>per</em> round of replication, <em>per</em> gamete, <em>per</em> cell division, etc. In a single gene sequence, the mutation rate can be estimated as the number of <em>de novo</em> mutations per nucleotide <em>per</em> generation. For example, in humans, the mutation rate ranges from 10⁻⁴ to 10⁻⁶ <em>per </em>gene <em>per</em> generation.
