An evolutionary theorist believes that large groups of organisms are related to each other by _________ while a design theorist believes that such groups are related to each other in _________ .
Answer:
blood
Explanation:
because it is good
The evolutionary theorist says about the relatedness in organisms is due to molecular phylogeny, while the design theorist that group are related to each other by morphological characteristics.
What is the role of molecular phylogeny in evolutionary studies?The molecular phylogeny is the way to find out whether the species has a common ancestor or they are different. It is studied on the basis of DNA sequencing and amino acid sequence.
This is correct as it gives exact data of evolution. But previously the theorist believed and grouped organisms based on morphological character.
The similar-looking organism was grouped into the same category as an animal, plant fungus. Which is not the correct way.
Thus, evolutionary theorists rely on molecular basis study to know about the closeness of an organism to other species.

Hydrolysis of a protein will lead to the formation of monosaccharides.
True
False
Answer:
True
Explanation:
Because it would do that.
Hydrolysis of a protein will NOT lead to the formation of monosaccharides.
Hydrolysis of protein leads to amino acids not monosaccharides because amino acid is the building block of proteins means protein is made up of amino acids while on the other hand, the hydrolysis of carbohydrates such as polysaccharide and disaccharide etc leads to monosaccharide. Various monosaccharide combine together forming polysaccharide and disaccharide so we can conclude that the statement is false.

Answer: the answer would be a
Explanation: because I had the same question too on acellus and got a right
Photosynthesis makes use of light energy while chemosynthesis is the main source of energy capture where light energy is not available.
What is photosynthesis?It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.
The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

What is used to classify volcanoes based on the strength of their eruptions?
The answer you are looking for is the VEI scale, also known as the Volcanic Explosivity Index. The scale ranges from 1-8. Volcanic eruptions are classified due to how much volcanic material is ejected into the atmosphere, the height of the plume cloud, and how long the eruptions last. For example, the eruption of Mount Tambora in 1815 was a VEI 7 and caused the year without a summer. Volcanic eruptions in VEI 6 and 7 ranges are really rare, but VEI 8 eruptions are the rarest. VEI 8 eruptions are known as super eruptions, and they happen around every 100,000 years. Sorry, I got a little bit carried away. But, anyways, the VEI scale is the correct answer.
a problem that confounds attempts to organize the entire living world for study?
Answer:
A problem that confounds attempts to organize the entire living world for study is the need of evolutionists to bring the entire diversity of living things ultimately into.
In biology, living things can all be classified in accordance with other living things that share a specified set of common characteristics. A major challenge to the process of classification is that, in evolution, that this involves the need to classify all living things. The challenges being that there are many species on planet earth that once existed and are now extinct (i.e. they cannot currently be studied in living form) and that there may be species that do exist that have yet to be discovered and therefore cannot be classified. Finally, due to the sheer number of species on earth, it will literally take hundreds of years for scientists to classify all species.
Cells typically keep the surface to volume ratio high. If a cell was a cube and you doubled the height and length of the cell, how much would the volume increase?

Answer:
It cannot be mixed with any other type of insulin
Explanation:
Glargine insulin is a long-acting basal insulin. This i the Option marked C
What is insulin?
A kind of insulin used to control diabetes is glargine insulin. It falls within the category of long-acting basal insulin. In order to meet the body's regular insulin requirements between meals and during fasting periods, basal insulins offer a gradual and consistent release of insulin over a lengthy period of time.
Glargine insulin maintains blood sugar control for a considerable period of time, usually up to 24 hours, with a generally steady and protracted action.
