You are overseeing a paleontological expedition at the Grand Canyon to uncover fossils. You have one group working about 10 feet above the bottom of the canyon,
uncovering a cluster of Brachiopods You have a second group working about 300 feet above the bottom of the canyon, uncovering impressions from a variety of plants
such as fems and horsetails. While you are waiting for the exact age of the rock layers to be determined, what can you tell about the age of the fossils based on
where they are
A. You cannot determine anything yet.
B. They are all about the same age.
C. The plants must be older than the Brachiopods.
D. The Brachiopods must be older than the plante
Answer:
C
Explanation:
because the plants are farther down lol
Paleontology establishes the geological age of the organisms. Based on the height of the fossils discovered at the Grand Canyon, it can be concluded that plants were older than the Brachiopods. Thus, option C is correct.
What are fossils?The dead remains and decaying materials of the plants and animals stored and preserved under the sediments and rock layers over a period of many years are said to be called fossils.
The fossils are evidence of the evolution as well are used to determine the geological age of the species based on their occurrence of them in the rock layers.
The fossils of plants like horsetails and ferns were found 300 ft above the Canyon while Brachiopods at 10 feet above Canyons that tell that plants were found earlier than the former species.
Therefore, option C. the plants existed prior to the Brachiopods.

Organ A is the heart, Organ B is the brain, and Organ C is the lungs
Organ A is the heart, Organ B is the lungs, and Organ C is the brain
Organ A is the lungs, Organ B is the brain, and Organ C is the heart
Organ A is the lungs, Organ B is the heart, and Organ C is the brain
Organ A is the heart
Organ B is the lungs
Organ C is the brain
Because heart only delivers blood to lungs and other body tissues, Lungs input oxygen into the blood and brain sends signals and messages to the body parts.

Genetic engineering involves various stages.
1 human DNA is inserted into bacterial plasmid DNA
2 recombinant plasmid inserted into bacteria

4 restriction enzyme cuts human DNA
What is the correct sequence for genetic engineering?
Answer:
4, 3, 1, 2
Explanation:
FIRST: cDNA is synthesized to be used as a gene of interest: processed (spliced) mRNA (no introns) is reverse transcribed to cDNA using reverse transcriptase, an enzyme from retroviruses
SECOND: Restriction enzyme used to cut GOI
THIRD: Same Restriction enzyme used to cut plasmid (sticky ends are created)
FOURTH: GOI connects/hybridizes with plasmid due to base-pairing
FIFTH: DNA ligase connects the recombinant DNA strands
ASAP What occurs after the homologous pairs are separated?
A. The sister chromatids separate.
B. Spindle fibers attach to the chromosomes.
C. Haploid cells are formed.
D. The nuclear envelope reforms.
Answer:
A
Explanation:
the sister chromatids separate
After the separation of homologous pairs, the sister chromatids are subsequently separated during meiosis II.
What is Homologous pair?Homologous pairs may be defined as those chromosomes which are very identical to one another and have the same size and shape.
In meiosis I, the separation of homologous pairs occurred. After this process, the sister chromatids are separated in meiosis II.
This separation leads to the production of a total of four products having the half number the chromosomes as compared to the original cell.
Therefore, the correct option for this question is A.

A. To recycle molecular building blocks
a
B. To break down photons
C. To gather green light
O D. To convert light energy into chemical energy
Answer:
OptionA because decomposers are associated
Explanation:
The role of the fungus in the food web shown is to recycle molecular building blocks. The correct option is A.
What is food web?A food web is a diagram that depicts the interconnection of various organisms in an ecosystem via the exchange of energy and nutrients.
The food web is made up of several interconnected food chains that represent the flow of energy from one organism to the next.
Fungi are decomposers that play an important role in breaking down organic matter and recycling nutrients in many ecosystems.
The fungus in the food web is most likely breaking down dead plant or animal matter, releasing nutrients like carbon, nitrogen, and phosphorus back into the soil.
These nutrients are then absorbed by plants, which are then consumed by herbivores such as the coati and sloth.
Thus, the correct option is A.

When does consumption begin to surpass supply?
Answer:
In about 625years
Explanation:
According to the graphical representation depicted in this question, it shows the supply and consumption of forests when the consumption rate and population growth rate are both low. The green line represents the total consumption while the red line represents the total supply.
Based on observation of the graph, the total consumption exceeds or surpasses the total supply at a little above 600 years. Approximately, this can be said to be in about 625years.
Answer:
In about 625 years
Explanation:
Consumption has definitely surpassed supply by 700 years, but it only begins to surpass it around the 625 year mark according to the graph

It is believed that the ratio of cyclic electron transport to Z-scheme photosynthesis changes in response to metabolic demands. If a plant were actively engaged in a large amount of reductive biosynthesis, requiring NADPH, how would it alter these processes compared to a plant just performing the Calvin cycle to produce glucose
Answer:
The correct answer is (b) More Z-scheme photosynthesis, less cyclic photophosphorylation
Explanation:
Z-scheme is the schematic flow of the electrons from water to NADP+ and as it connects the two different photosystems that look like z in the diagram it is termed as Z-scheme of photosynthesis. The ratio of cyclic electron transport to Z-scheme photosynthesis alters as per the metabolic requirements. In the question, it is given that If a plant were actively engaged in a large amount of reductive biosynthesis, requiring NADPH, then it will acqiuire more z-scheme photosynthesis compared to a plant just performing the Calvin cycle to produce glucose.
Answer: More Z-scheme photosynthesis, less cyclic photophosphorylation

A bacterial cell wall is composed of: A) A polysaccharide consisting of a single type of monosaccharide unit and cross-linking oligopeptides. B) A polysaccharide consisting of 2 types of monosaccharide units and cross-linking oligopeptides. C) A polysaccharide consisting of 3 types of monosaccharide units and cross-linking oligopeptides. D) Two different polysaccharides and 1 type of oligopeptide, which are cross-linked.
Answer:
B) A polysaccharide consisting of 2 types of monosaccharide units and cross-linking oligopeptides.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
Also, a unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
A bacterial cell is made up of peptidoglycan and its main function is to maintain the shape of a cell while preventing it from bursting due to osmotic pressure. Also, the bacterial cell inhibits the passage of larger molecules but allows the free movement (passage) of smaller molecules in the body of a living organism.
Basically, bacterial cell wall comprises a polysaccharide that's typically made up of two (2) types of monosaccharide units and cross-linking oligopeptides.
