Identify the strengths and weaknesses of Mendel’s Law of Independent Assortment.
Answer:
Explanation:
Mendel propel two laws The law of inheritance and that of independent assortment of gene.
Independent assortment of gene explain that alleles of a gene assort independently and that different Allele can show different phenotypic effect and differences. This means that in a gene where we have 2 allele they can both show individual difference where one can have a dominant effect over the other and the other allele is recessive.
This law does not take care of linked gene where alleles don't separate after crossing over sister chromatids but are rather inherited together given rise to complex inheritance.
Pleiotrophy effect of a gene where a gene is having many effects.
What do scientists believe provides evidence for the Big Bang theory?
A. The gradual spreading of the ocean floors along plate boundaries
B. the presence of the main asteroid belt
C. The core accretion theory of planet formation
D. The presence of cosmic microwave background radiation?
The presence of cosmic microwave background radiation is evidence for the Big Bang theory given by scientists. The correct option is D.
What is Big bang theory?The Big Bang theory exemplifies how the universe came into existence from a high density and temperature starting point.
It is the dominant cosmological model that explains the evolution of the observable universe from its earliest known periods to its subsequent large-scale form.
According to scientists, the universe should be filled with radiation that is literally the remnant heat from the Big Bang, which is known as the "cosmic microwave background," or CMB.

10. Which of the following groups of organisms are prokaryotic? (Choose all that apply)
Archaea
Or
Plants
Or bacteria
Or fungi
Answer:
Archaea bacteria
Explanation:
just search each answer choice asking if its eukaryotic or prokaryotic and it will tell you
Bacteria and Archaea are groups of organisms that are prokaryotic, which means that their cells do not have cellular organelles or a delimited nucleus in the cytoplasm.
The prokaryotic cell is characterized by not having a cell nucleus, therefore its ribosomes are smaller and its genetic material simpler.
Prokaryotes are, in most cases, unicellular microorganisms.
The bacteria is a unicellular and prokaryotic microorganism, which means that it does not have a nucleus, they are a few micrometers long and various shapes including spheres (cocci), rods (bacilli) and helices (spirils).
A diversity of unicellular microorganisms that make up the archaea kingdom lacking nuclei (prokaryotes) is known as archaea.
Their cells are surrounded by a covering (cell wall) made of various materials that give them high resistance against antibiotics or other harmful substances.
Therefore, we can conclude that bacteria and archaea are groups of organisms that are prokaryotic, which do not have a defined nucleus and or organelles surrounded by a membrane.
