5) Describe crossing-over. When does crossing-over occur? What is the result?
Answer:
Crossing over occurs between prophase I and metaphase I and is the process where two homologous non-sister chromatids pair up with each other and exchange different segments of genetic material to form two recombinant chromosome sister chromatids.

While on a field trip, your teacher asks you to record the names of any species you see and to tally the number of individuals of each species you see. What has the teacher asked you to investigate? a. ecosystem diversity c. habitat diversity e. species diversity b. genetic diversity d. structural diversity
Answer:
Hi how are you doing today Jasmine
The teacher has asked you to investigate the species diversity. Thus, the correct option is E.
What is Species?Species may be defined as a cluster of organisms that can reproduce with one another in nature and produce fertile offspring.
Species diversity is the sum total of all species present in an ecosystem. It may also be described as the number and relative abundance of species present in a given biological organization.
Therefore, the teacher has asked you to investigate the species diversity. Thus, the correct option is E.

3. Which organism has DNA located in three organelles?
A. A sponge
B. A fern plant C. A flatworm
D. A bacterium
In a FERN PLANT, DNA is located in three different organelles (Option B).
Plants are organisms that have chloroplasts, mitochondria, and cell nuclei.In a eukaryotic cell, the genetic material (i.e., DNA) is mainly found in the nucleus, which is an organelle bounded by a double-membrane (bacteria don't have nuclei).However, mitochondria and chloroplasts are also membrane-bound organelles that have their own genetic material.Chloroplasts are only found in plants and algae (sponges and flatworms don't have chloroplasts).In conclusion, in a FERN PLANT, DNA is located in three different organelles (Option B is correct).

if a vector not have origin of replication result in what
Answer:
What will be the consequence of not having an origin of replication (ori) in the vector? Explanation: In the case ori is absent, the vector won't be able to replicate
Explanation:
As the replication won't take place, only one of the daughter cells would be having the vector. A colony of transformed colonies won't be obtained.
if a vector does not has the origin of replication result in not doing replication as the unit of replication is Ori.
In the case Ori is absent, the vector may not be capable of replicating. As the replication may not take place, the handiest one of the daughter cells might be having the vector. A colony of converted colonies may not be obtained.
What is transgene?
Of these, the maximum usually used vectors are plasmids. Common to all engineered vectors have a foundation of replication, a multi cloning site, and a selectable marker. The vector itself is normally a DNA series that includes an insert (transgene) and a bigger series that serves as the "backbone" of the vector.
Thus it is clear that if a vector does not have an origin of replication result in nonreplicating.

What is the function of Stomata?
Answer: Stomata, the small pores on the surfaces of leaves and stalks, regulate the flow of gases in and out of leaves and thus plants as a whole. Stomata are composed of a pair of specialized epidermal cells referred to as guard cells (Figure 3). Stomata regulate gas exchange between the plant and environment and control of water loss by changing the size of the stomatal pore.

Geranium leaves grow in positions that permit the optimum use of light as a result of
Answer:
do you work stop cheat broo this evan btw
Explanation:
Geranium leaves are typically arranged in a way that allows for optimal use of light through a process called "heliotropism" or "solar tracking."
What is heliotropism?Heliotropism is the ability of plants to orient themselves towards the direction of the sun to optimize their exposure to light.
Geranium leaves are arranged in a rosette pattern, with each leaf emerging from the base of the stem and spreading outwards. The leaves are arranged in a way that maximizes their surface area while minimizing shading of other leaves. This arrangement allows the leaves to capture the maximum amount of sunlight possible.
Additionally, geranium leaves have a waxy cuticle that helps to prevent excessive water loss and damage from UV radiation. The leaves also have chloroplasts, which contain chlorophyll and are responsible for photosynthesis, the process by which plants use sunlight to produce energy.

Into which of the six kingdoms should the organism be placed? Construct a response to state your claim, use evidence, and support with reasoning. Include the list of common characteristics of the kingdom and why it does not belong in the other kingdoms in your justification.
Answer:
Protist kingdom
Explanation:
The organism in the picture is an amoeba nd it belongs to the protist kingdom.
Amoeba does not have cell wall or a chloroplast and so it cannot be named under the plantae kingdom. It cannot be placed under Archaebacteria or bacteria as the organism has a nucleus. It also contain a psedupodium, so it can be placed under fungi or the animalia kingdom.
Why are there two numbers normally given when determining blood pressure?
Answer:
Both numbers are equally important and you need both. There are two because you need both.
Explanation:
When you go to take your blood pressure the top number is the systolic pressure and it measures the amount of pressure in your arteries during the contraction of your heart muscle. The bottom number is called the dialostic pressure and measures the amount of blood pressure of you heart muscle between beats. Healthy blood pressures numbers are 120 over 80, or 120/80.
When one DNA molecule is copied to make two DNA molecules, the new DNA contains 50% of the parent DNA. Why?

a. it receives no radiation
b. it is immune to insolation
c. it has a high albedo
d. it has no heat capacity
Gypsum, a soft mineral frequently left behind when water bodies evaporate, is what gives the sands of White Sands National Monument a high albedo their texture, hence option C is correct.
What is white sands national monument?Despite being a very common mineral, gypsum is rarely found as sand because it readily dissolves in water and is often transported to the sea by rivers.
The dunes seem white like snow additionally, gypsum doesn't absorb heat from the sun as silica sand does.
Therefore, gypsum is actually a transparent material, but due of the frequent collisions between the grains,, hence option C is correct.
