Cytoplasm is randomly distributed to haploid cells.
True/false
False. Cytoplasm is not randomly distributed to haploid cells.
Haploid cells refer to cells that have a single set of chromosomes, as opposed to diploid cells that have two sets. The process of cell division, called mitosis, is responsible for the distribution of cytoplasm and chromosomes to the new cells. The cytoplasm and chromosomes are divided equally between the two daughter cells. The process is highly regulated and orchestrated to ensure that the cells have the correct amount of cytoplasm and chromosomes to function properly. It's important to note that, in some cases, in some organisms, such as fungi, there is a process called plasmogamy, where cells fuse, but their nuclei do not, resulting in a cell with multiple nuclei but a single cytoplasm.

r-selected species, also called r-strategist, species whose populations are governed by their biotic potential (maximum reproductive capacity, r). Such species make up one of the two generalized life-history strategies posited by American ecologist Robert MacArthur and American biologist Edward O. Wilson; K-selected species—that is, species whose population sizes fluctuate at or near their carrying capacity (K)—make up the second strategy.
The production of numerous small offspring followed by exponential population growth is the defining characteristic of r-selected species. They require short gestation periods, mature quickly (and thus require little or no parental care), and possess short life spans. Unlike K-selected species, members of this group are capable of reproduction at a relatively young age; however, many offspring die before they reach reproductive age.

what is photosynthesis ?
Photosynthesis is a process that plants and other organisms utilise to transform light energy into chemical energy that may then be released to power the organism's activities via cellular respiration. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are created from carbon dioxide and water - thus the name photosynthesis, from the Greek "putting together". Photosynthesis is performed by the majority of plants, algae, and cyanobacteria; these organisms are known as photoautotrophs. Photosynthesis is responsible for creating and maintaining the oxygen content of the Earth's atmosphere, as well as supplying the majority of the energy required for life on Earth.

An atom of iron has an atomic number of 26 and a mass number of 56. How many protons plus neutrons are in the nucleus?.
The number of protons in an atom is also referred to as the atomic number, so an atom of iron has 26 protons in its nucleus. The mass number of an atom is the sum of the number of protons and neutrons in the nucleus. So, to find the number of neutrons in the atom, we can subtract the number of protons (26) from the mass number (56):
56 - 26 = 30 neutrons.
So, the number of protons plus neutrons in the nucleus is:
26 protons + 30 neutrons = 56.

Which of the following statement is true regarding natural selection?ANatural selection may lead to evolution.BDifferences in reproduction and survival are due to variation among organisms.CThe initial population varies in many traits. Individuals have one version of some traits.DAll of the above.
Option d is Correct. Darwin introduced the concept of natural selection (survival of the fittest). This hypothesis contends that more people are created with each passing generation, and they fight for survival.
Phenotypic variation exists among individuals and the variation is heritable; those individuals with heritable traits that are better suited to the environment will survive and reproduce. Those individuals that can inherit the adaptations according to the change in the environment will survive, and the rest will die.
Differential reproduction is what is done in this situation. At the time of reproductive isolation, new species (evolution) will develop. Natural selection is demonstrated by the industrial revolution in the black peppered moth.

victims of drowning who have stopped breathing are sometimes revived by a process called artificial respiration. Suggest why a biologist would object to the use of this expression. (Resuscitation is a better word to use.)
When a person experiences a drowning incident and stops breathing, immediate intervention is necessary to provide oxygen to the brain and other vital organs to prevent permanent damage or death.
Traditionally, this intervention has been called "artificial respiration" or "mouth-to-mouth resuscitation," where a person provides breaths to the victim by blowing air into their mouth to mimic the process of respiration. However, the term "artificial respiration" can be misleading because the action performed during resuscitation is not a complete replacement of the biological process of respiration as it occurs naturally in a living organism. Instead, it is an external intervention to provide oxygen to the victim until they can resume normal breathing on their own.
A more accurate and biologically precise term for this intervention is "resuscitation" or "cardiopulmonary resuscitation" (CPR). Resuscitation involves a combination of chest compressions to maintain blood circulation and rescue breaths to provide oxygen to the victim. By using the term "resuscitation," biologists and medical professionals can better convey the concept that the goal is to restore the natural processes of breathing and circulation, rather than implying the creation of an entirely "artificial" biological function.
