The correct answer for this question is A. Law of segregation.
All individuals have two alleles for a given trait. According to Mendel's Law of segregation, these alleles are passed down one each from both mother and father.
Explanations;
According to this law of segregation the allele pairs separate or segregate during the formation of gamete, during the process of meiosis, leaving each cell with a single allele for each trait, and randomly unite during fertilization. One pair of allele comes from the mother while the other pair comes from the father, and joins together to form a diploid cell. Therefore, organisms inherit two alleles for each trait one from each parent.
Answer: Male
Explanation:
The pelvis is narrow in males, the pubis arch is 90 degrees in angle. It is broad in case of females to support pregnancy and child birth. Also the pubis arch is more than 90 degrees in angle. An occipital protuberance is a region that connects the head to the neck and it is generally larger in males than in female. In males the forehead is sloping in the cranium whereas that in females it is vertical and flat.
Hence, the skeleton have the features that can be indicated towards the features of a male.
Answer:
Answered below.
Explanation:
The nerve fibres of the autonomic nervous system that connects the ganglia to the the central nervous system are called preganglionic fibres. They are divided into sympathetic preganglionic fibres and parasympathetic preganglionic fibres and both have acetylcholine as their neurotransmitter.
The sympathetic preganglionic is shorter compared to the parasympathetic preganglionic fibres. They originate from the hypothalamus and brainstem and project to the ganglia non the spinal cord. A ganglion is a cluster of nerves outside the central nervous system.
The preganglionic sympathetic fibres originating from T1-T2 innervate the cervical ganglion which innervates the muscles of the pupils (dilators).
The postganglionic fibres originating from the preganglionic fibres of T11-L3 passes through splenic, celiac and mesenteric ganglia to innervate the kidneys and renal vessels.
The answer is D. the way organisms grow and develop
