Explanation:
Heterozygous means that the organism has different alleles (L1)
Draw a punnet square:
L 1
L LL L1
1 L1 11
11 is the allele for short legs so 1 in 4 of the outcomes will lead to an offspring with short legs
Why do large organisms require a transport system?
Answer:
The surface area to volume ratio of an organism decreases as its size increases. Ultimately helps organisms, but at the other hand, can't move across the membrane on its own to bring materials like nutrients and water in their cells, or to remove waste material. Specialized transport systems are required for large multicellular organisms.
Explanation:
what is an ecosystem?
Answer:
An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. These biotic and abiotic components are linked together through nutrient cycles and energy flows
a biological community of interacting organisms and their physical environment.
Select the correct image.
Which image best illustrates the magma convection currents within Earth’s interior?
Answer:
the thrid one is the best one
The image that best illustrates the magma convection currents within Earth’s interior is the bottom left.
What is Convection?Convection may be defined as a process through which the transfer of heat due to the bulk movement of molecules within a fluid takes place. The current which is produced by the movement of these molecules is known as the Convection current.
Convection currents are present in the mantle region of the earth's surface. In the process of heating, magma rises from deep inside the mantle and then cooled the mantle as it flows down. This cyclic movement of magma constructs convection current within the region of the earth's interiors.
Therefore, the image that best illustrates the magma convection currents within Earth’s interior is the bottom left.

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).

Match the following terms with the correct definition. Arterioles Arteries Capillaries Venules Veins Small vessels that carry blood away from the heart to the capillaries are __________. Muscular-walled vessels that carry blood away from the heart are _______. One-cell-thick microscopic vessels that function to exchange nutrients and wastes are _________. Small vessels that connect to the capillaries that carry blood back to the heart are ________. Vessels that carry blood back to the heart are _________.
Answer:
Small vessels that carry blood away from the heart to the capillaries are Arterioles. Muscular-walled vessels that carry blood away from the heart are Arteries. One-cell-thick microscopic vessels that function to exchange nutrients and wastes are Capillaries. Small vessels that connect to the capillaries that carry blood back to the heart are Venules. Vessels that carry blood back to the heart are Veins.
Explanation:
We have different types of vessels in our bodies. We can divide them by their size and structure. Starting from the ones that carry blood away from the heath, we have the arteries. Arteries are vessels of big diameter that have muscle around them. Then, the arteries branch into arterioles, which have a smaller diameter. The arterioles branch into capillaries. These are small vessels with thin walls that allow the exchange of nutrients, wastes, and gases with the neighboring tissues. Once that the blood flows through the capillaries, it goes to the venules, which are small veins that will carry the blood to the veins and these to the heart. The veins do not have muscles in their structures, and their walls are thinner than the ones in the arteries.
Why was the evolution of cyanobacteria such a significant event in Earth's history?
Answer:
Cyanobacteria are blue-green algae that produce chlorophyll and undergo photosynthesis. Oxygen, a byproduct of that photosynthesis, was released into the atmosphere, changing it in such a way that it may have allowed the evolution of more complex forms of life.

Vacuoles are cellular organelles that are found in all plant and fungal cells. In plant cells, vacuoles tend to store large amounts of water, so they can push outward on cell walls and help keep plants upright. In fungal cells, vacuoles often store materials that are toxic to the cell.
According to the above information, how do vacuoles help fungal cells maintain homeostasis?
A.
by storing large quantities of water
B.
by allowing the cells to get rid of waste
C.
by producing more cellular organelles
D.
by helping the cells extract energy from food
Answer:
D. by helping the cells extract energy from food
Explanation:
Fungi are decomposers so they normally need some sort of food to grow. To get the energy to grow, they extract it from the food. Fungi will get their energy from dead animals, dead plants, etc.
Which type of reproduction produces offspring with more genetic variations?
(Include the terms "mitosis" and "metosis" in your answer)
Answer: Meiosis
Explanation:
Mitosis results in clones that are genetically identical to their parents. Meiosis has processes like crossing over and the law of independent assortment which allow for genetic variatoin and recombinants.

Most cells in our body have two versions of each chromosome (Body cells). These cells are called diploid. We grow and replace these cells with identical cells through a cell division called mitosis.
For sexual reproduction, we need to make cells that have only one version of each chromosome (sex cells). These cells are called haploid. These unique cells are made through a cell division called meiosis.
Explanation:
haploid = 1
diploid= 2 // "di"=2
our body contains 46 chromosomes, half from our dad and a half from our mom. our repoductive contains 23 chromosomes.

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.
