HAIR ANALYSIS
An investigator is excited to find a hair with the follicle attached when searching for evidence at a crime scene. Explain why the investigator might be excited.
The fact they hair follicles contains cellular materials rich in DNA will give them a strong lead in their investigation. Hence, the excitement.
The bottom of the hair follicle marks the point where hair growth begins, Investigators are often helped in their crime research by the outcome of DNA test. Therefore, investigators often seek materials or elements at crime scenes which could be evaluated to gives DNA result of potential suspects.Therefore, the fact that hair follicles contain cellular materials which are rich in DNA, will excite investigators as that have obtained a key lead in their investigation.

What are the important considerations during the classification of nematodes?
Answer:The Nematoda, similar to most other animal phyla, are triploblastic, possessing an embryonic mesoderm that is sandwiched between the ectoderm and endoderm. They are also bilaterally symmetrical: a longitudinal section will divide them into right and left sides that are symmetrical.

How does the population growing negatively impact earth
Well as the population grows, our resources start to decrease. More resources are wasted every single day of our lives and we still keep digging them all out, what makes it worse is, since animals keep going endangered, humans keep coming and coming and if it keeps happening we will have no animals. Not to mention people are burning forests, the things we need to breathe.

What is the probability of short beaks in the offspring of the cross show above
Answer:
8/16 or 1/2
Explanation:
This question is a dihybrid cross involving two genes, one coding for feather color and the other for beak length. The alleles for green feathers (G) and long beak (L) are dominant over the alleles for yellow feathers (g) and short beak (l).
According to this question, a male with genotype GGLl was crossed with a female with genotype Ggll. The following combination of gametes is produced by each parent:
GGLl - GL, Gl, GL, and Gl
Ggll - Gl, Gl, gl and gl
Using these gametes in a punnet square (see attached image), the following offsprings in the following proportions will be produced.
Green feathers, long beak (GGLl, GgLl) = 8/16 or 1/2
Green feathers, short beak (GGll, Ggll) = 8/16 or 1/2
Hence, the probability of short beaks (ll) in the offspring of the cross is 1/2.

During the process of DNA replication, a complementary DNA strand is formed. If the original strand of DNA is 5 ATA GTG CCC AAC GGT 3 which of the following would be the correct complementary DNA strand?
3. ATA GTG CCC AAC GGT 5
3 TAT CAA GGG TTG CCA 5
3 TAT CAC GGG TIG CCAS
3 TAT CAC GGG TTG CCT 5
Answer:
the third one
Explanation:
DNA replication produces two duplicated semi-conservative daughter strands. The complementary DNA strand of the original sequence will be, TAT CAC GGG TTG CCA. Thus, option c is correct.
What is DNA replication?DNA replication is the process where the parent DNA strand forms two daughter strands that are semi-conservative and complementary to the DNA molecule. The complementary base pairing rule is used to produce the leading and lagging strand.
The complementary base pairing rule states the bonding between a purine and pyrimidine molecule. Accordingly, adenine base pairs with thymine, and guanine base pairs with cytosine.
Parent strand: 5' ATA GTG CCC AAC GGT 3'
Complementary strand: 3' TAT CAC GGG TTG CCA 5'
Therefore, option c. 3' TAT CAC GGG TTG CCA 5' is the complementary sequence.

Which statement best summarizes how the light-dependent reactions and light-independent reactions (Calvin cycle) work together during photosynthesis
The light-dependent reactions capture energy and the light-independent reactions use that energy to make glucose
The light-dependent reactions capture energy and the light-independent reactions use that energy to make ATP
The light-dependent reactions take in glucose (food energy) and the light-independent reactions use the glucose to make ATP
The light-dependent reactions capture bees and the light-independent reactions blend those bees up into golden cheddar mac and cheese... watch
out for the stingers though
The light-dependent reactions take in glucose (food energy) and the light-independent reactions use the glucose to make energy in the form of
sunlight
The light-dependent reactions capture energy and the light-independent reactions use that energy to make glucose
The energy captured in the light-dependent reactions is stored in ATP and NADPH and is used in Calvin's cycle to fixateCO2 in order to synthesize glucose

What can you conclude about the structure of mitochondria?
Answer:
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate
Explanation:
hope that helped ;/
Answer:
Mitochondria are shaped perfectly to maximize their productivity. They are made of two membranes. The outer membrane covers the organelle and contains it like a skin. The inner membrane folds over many times and creates layered structures called cristae
1. One positive use of viruses is their function as a. infectious particles. c. cloning vectors. b. pandemic initiators. d. marine predators.
Answer: The correct option is C.
Cloning vectors.
Explanation:
Viruses are use as cloning vectors because they can give the new gene or birth the new gene by infecting the cell. They are so modified and orogrammed in such a way that they cannot cause disease when it is used in humans. Cloning vector is a DNA fragment gotten from viruses or bacteria plasmid which is maintained and used for cloning purposes.

Metamorphic rocks are a bit harder to identify because they can share traits with the other rock types. Again, thinking about the formation process can help. Metamorphic rocks have been heated and squashed. This can lead the minerals in them to line up, creating ribbon-like layers called bands. These rocks are called foliated metamorphic rocks. You can see these bands in gneiss. If a metamorphic rock has fossils, you know it was formed from a sedimentary rock. Because of the heat and pressure, the fossil will be hard to recognize and out of shape.
Which of the following best describes foliated metamorphic rocks?
A
There are easily recognizable fossils.
B
The rock has ribbon-like layers of bands.
C
They have crystals like igneous rocks.
D
Different sized sediments can be see
Answer:
b
Explanation:
the fourth sentence in the passage: "This can lead the minerals in them to line up, creating ribbon-like layers called bands."
Dark and light bands may alternate due to the separation of mafic (dark) and felsic (light) minerals. Having different grain sizes in the same mineral can also result in banding. Thus, option B is correct.
What are the ribbon layer present in the rock?Under the surface of the earth, metamorphic rocks are formed. The extreme heat and pressure cause them to alter. Their layers resemble ribbons. Some of them are covered in bright crystals.
Under the earth's surface, metamorphic rocks are created as a result of the transformation brought on by extreme heat and pressure (squeezing).
These processes produce rocks that frequently have layers that resemble ribbons and may have glittering crystals on their surface that were created by minerals slowly growing over time.
Therefore, This can lead the minerals in them to line up, creating ribbon-like layers called bands

Answer:
To be sustainable is to be able to maintained at a certain rate. It's to keep things continuous and viable.
