Answer:

not significant to the overall mass of the atom

Explanation:

The mass number of an atom is the combination of the mass of the protons and neutrons.  Electrons are not included because their mass are so insignificant that is doesn't change the total mass much, therefore they are left out. The mass of an electron is about 1,830 times smaller than protons and neutrons.

Which best describes how waste is secreted in each system
Alex777 [14]

Answer:

The digestive system excretes a solid waste, and the excretory system excretes liquid waste.

Explanation:

The digestive system is the system of the body that breaks down food substances to enhance so that they can absorb them. But it also excretes solid indigestible substances. For excreating, they use the defecation process.

Excretory system, on the other hand, is a system in the body that removes homeostatic wastes from the body by using a process which is called excretion. Excretory includes organs such as liver, sweat glands, lungs. Among this, the liver plays a critical role in the secretion of homeostatic wastes in the form of fluids.

The excretory system collects and then filters excess water which is present in the body and then excretes it as a liquid waste either from the liver, kidneys, or sweat glands on the skin through sweating.

1. _________reproduction is a means of creating new individuals solely by________ the form of cell division that creates genetic
mixer [17]

Answer:

1. asexual, mitosis  2. sexual  3. gametes, meiosis  4. haploid 5. sex cells

Explanation:

Asexual reproduction is the form of reproduction that occurs whereby there is no fusion of gametes or a change in the number of chromosomes. The produced daughter cells are genetically similar to the parent. the form of cell division that occurs here is through a process of mitosis.

Different organisms adopt different type of asexual reproduction including binary fission, spore formation, fragmentation etc.

Sexual reproduction in contrast generates genetically unique organism through the fusion of two different organisms sex cells. To accomplish sexual reproduction, gametes that are haploid through a process of meiosis must be produced which are the egg cell and the sperm cells (the sex cells). These haploid cells are produced only in the germ cells to ensure the production of a diploid zygote.
