Answer:
There are four different types of chromosomal mutations: Deletions, Translocations, Duplications and Inversions (pictured below). Note that any chromosome mutation resulting in a significant loss of genetic material (Deletion) is most likely to be lethal.
deletion is where a section of a chromosome is removed.
translocation is where a section of a chromosome is added to another chromosome that is not its homologous partner.
inversion is where a section of a chromosome is reversed.
duplication occurs when a section of a chromosome is added from its homologous partner.
Chromosome mutations are often lethal as the chromosome structure is altered.

ASAP!! In the past, plants and fungi were classified together into a single kingdom. What new scientific knowledge led to their current classification into separate kingdoms?
A. It was discovered that plants do not function as decomposers in ecosystems.
B. It was discovered that fungi lack body structures for locomotion.
C. It was discovered that plants could be unicellular.
D. It was discovered that fungi are heterotrophic.
Answer:
D
Explanation:
fungi are heterotropic therefore they cannot produce their own food. plants can since they are autotrophic
The new scientific knowledge led to their current classification into separate kingdoms as It was discovered that fungi are heterotrophic. Thus, option D is correct.
What are fungi?Fungi and plants are currently classified into two distinct kingdoms. However, due to some of their common observed features, they were once classified together as one kingdom. Fungi are a group of heterotrophic organisms that possess cell well while Plants are group of autotrophic organisms that also possess cell wall.
Previously, the observable similar features were the basis of classification of organisms. It was observed that fungi and plants were nonmotile i.e. cannot locomote, and possessed a fixed body structure that grew out of the soil (fungi mushroom).
Therefore, The new scientific knowledge led to their current classification into separate kingdoms as It was discovered that fungi are heterotrophic. Thus, option D is correct.

1. Binary fission is observed in (a) Hydra (b) yeast (c) Amoeba (d) human being
Answer:
Amoeba
Explanation:
Binary fission is a type of asexual reproduction in which a cell divides to form two cells. It occurs in organisms that are protozoans. This means that two new daughter cells are formed in the process.
During the process of binary fission, the cell Is divided into two, this means that the DNA is replicated in both parts so that each of these cells becomes an independent organism, this means that they would be able to survive and function on their own.
Hence from the options listed, binary fission is observed in Amoeba

compare and contrast the rock cycle and the carbon cycle
Answer:
The rock cycle and water cycle overlap with erosion, transporting, and deposition.carbon atoms are used repeatedly on Earth and cycled between the atmosphere, hydrosphere, biosphere, and lithosphere through processes
Explanation:
The rock cycle and the carbon cycle are two different types of natural cycles that occur on earth. The difference include components, processes, time scale, human impact, and environmental implications.
What is the difference between rock cycle and carbon cycle?The rock cycle is a continuous process that occurs over millions of years, during which rocks are transformed from one type to another. There are three major types of rocks: igneous, sedimentary, and metamorphic. Each type of rock is formed through a different process.
The carbon cycle is the process by which carbon is cycled between the atmosphere, oceans, and living organisms. Carbon is essential for life, and is found in all living organisms. The carbon cycle is driven by photosynthesis, respiration, and decomposition.
During photosynthesis, plants absorb carbon dioxide from the atmosphere and use it to build organic molecules. These organic molecules are then consumed by other organisms, and carbon is transferred up the food chain.
When organisms die, their bodies are decomposed by bacteria and fungi, which release carbon dioxide back into the atmosphere.
In addition, carbon is stored in fossil fuels such as coal, oil, and natural gas, which are formed from the remains of ancient plants and animals. When these fuels are burned, carbon is released into the atmosphere, contributing to global warming.

what does the chromatin do in the cell?
Answer: it's Chromatin
because Chromatin is a substance within a chromosome consisting of DNA and protein. The DNA carries the cell's genetic instructions. The major proteins in chromatin are histones, which Chromatin is located in the nucleus of our cells. The primary function of chromatin is to compress the DNA into a compact unit that will be less voluminous and can fit within the nucleus. Chromatin consists of complexes of small proteins known as histones and DNA. hope this helps have a nice day ❤️❤️❤️

This external structure is often a feature of bacterial pathogens; it aids in allowing the bacterium to counteract the body's immune system cells, such as avoiding phagocytosis.
Answer:
Bacteria capsule.
Explanation:
The bacteria capsule is a layer of polysaccharides that is around the bacteria membrane. Its principal function is to protect the bacteria from dehydration, destructive toxins, and cells that can destruct the bacteria, such as phagosomes. As a result, the bacteria have a higher probability of surviving and colonizing.

Control of rickettsial infections requires _____.
regular bathing
antibiotics
insect control
quarantine
Answer:
insect control
Explanation:
The control of rickettsial infections requires the control of insects.
Rickettsial infections are caused by obligately intracellular Gram-negative bacteria that can only live inside a host organism. The host organisms are usually insects such as ticks, fleas, lice, etc. and a bite from any of the insects hosting the bacteria represents the only through which the infections are transmitted.
Hence, controlling the insects that serve as hosts for the bacteria will go a long way in controlling rickettsial infections.
