Pls, help me with this question

Answer:

25%

Explanation:

If a parent is heterozygous, it has 2 difterent alleles. Both parents are heterozygous for blood type A, so the genotype is AO. A masks the O because A is dominant over O, so A is the blood type.

Create a punnett square to find possible offspring

AA = Blood type A

AO = Blood type A

OO = Blood type O

There is 1 child out of 4 that have blood type O. So to find the percentage divide 1 and 4 and multiply by 100.

1÷4×100 = 25

Answer:

Explanation:

The genotypes in the offspring of the p-generation, i.e. F1, are

Hh (hetero-zygous) short hair

hh (homo-zygous) long hair

each with 50%

However, when Hh crosses with hh, the proportion of the F1 should be 50% each of long and short hair.  The diagram shown does not seem to be consistent with realigy.

Answer:

When the bladder becomes full, the stretch receptors of the detrusor muscle send a signal to the pons, which in turn notifies the brain. People perceive this signal (bladder fullness) as a sudden desire to urinate, or urinary urge

Explanation:

Sharks gills are located on the side of their bodies while on the other hand, Skates have gills that are located in underneath of their mouth. In sharks , large spiracles are present on the ventral sides of shark's head whereas in Rays or Skates, spiracles are large in size and located on the dorsal side of their head. Spiracles is an external respiratory opening, located behind the eye of a cartilaginous fish.

Answer:

ground penetrating radar

Ground penetrating radar technological tool helps earth scientists gain new knowledge about earth’s subsurface. Thus the correct option is C.

Ground penetrating radar detects non-metal and metal objects, as well as voids and underground irregularities. It makes possible to measure the depth, dimensions, thickness of targets. It provides data quickly and can cover a large site area.

Ground penetrating radar can go deep up to 100 feet (30 meters) in low conductivity materials such as dry sand or granite. Moist shale, clays, and other high conductivity materials, may attenuate or absorb GPR signals, greatly decreasing the depth of penetration to 3 feet (1 meter) or less.

Answer:

Option 1: XnY

Explanation:

X-linked recessive traits can occur in both males and females. Since its recessive it needs both XnXn in females to show up but for males who are hemizygous (XY) they only need a defective copy of Xn for the disease to show up thus option 1 is correct.

I have added a helpful illustration below where we are talking about another x-linked recessive condition in humans: hemophilia.

Answer:

I don't know your reasons on how you would feel about becoming an astrobiologist but this is what I found and my feelings.

Explanation:

The Perseverance twin is called Optimism.  This has all of the same electronics as Perseverance and it’s important to have a twin so that they can test things before they operate Perseverance.  When they do land on Mars they need the twin to test out all of the sequences and plan that they have for the rover before they send them up to Perseverance on the surface of Mars.  Also, if they have a problem with Perseverance it gives them a place to practice how they recover from that problem.  

Personally, for me, I would not like to become an astrobiologist.  I like science but not that much.  I like the simple questions of why and how does it work.  I’m not entirely sure that we as humans are meant to be on any other planet except earth.  Earth has been here for many many years and seems to reset itself.  I don’t care why and will never know why in my lifetime.  I’s just not something that I like to considerate doing as a career.

NASA is targeting no earlier than April 8 for the Ingenuity Mars Helicopter to make the first attempt at powered, controlled flight of an aircraft on another planet. Before the 4-pound (1.8-kilogram) rotorcraft can attempt its first flight, however, both it and its team must meet a series of daunting milestones.

Ingenuity remains attached to the belly of NASA’s Perseverance rover, which touched down on Mars Feb. 18. On March 21, the rover deployed the guitar case-shaped graphite composite debris shield that protected Ingenuity during landing. Ingenuity is battery powered and completely sef recharging from the solar panel on the top.  The rover currently is in transit to the “airfield” where Ingenuity will attempt to fly. Once deployed, Ingenuity will have 30 Martian days, or sols, (31 Earth days) to conduct its test flight campaign.  All data and pictures will  be transmitted to Perseverance and then uploaded for all to see.

Explanation:

Competition for resources like food and space cause the growth rate to stop increasing, so the population levels off. This flat upper line on a growth curve is the carrying capacity. The carrying capacity (K) is the maximum population size that can be supported in a particular area without destroying the habitat.

Answer:

Reasons why they're different :

Explanation:

1. Mitosis is reserved for somatic cells while meiosis is reserved for sex cells (gametes).

2. Mitosis results in identical cells , while meiosis results in genetically distinct cells.

3. Mitosis undergoes one round of cell division while meiosis undergoes two rounds of divison.

4. Mitosis results in diploid daughter cells, while meiosis results in haploid daughter cells.

5. Unlike mitosis, meiosis differs in males and females.

6. Mitosis creates a human cell with 46 chromosomes, while meiosis creates a human cell with 23 chromosomes.

Answer:

A. Out of the cell. They want to move from high to low concentration (DOWN the concentration gradient)

Explanation:

Although the cuticle provides important protection from excessive water loss, leaves cannot be impervious because they must also allow carbon dioxide in (to be used in photosynthesis), and oxygen out. These gases move into and out of the leaf through openings on the underside called stomata (Figure 3b).

Answer:

Explanation:

One way that Julio can explain such differences is that their environments are very similar and therefore the traits that were best suited for their survival were passed on from generation to generation. The traits that each species developed differently would have been due to their diet. Each species has a different diet and certain traits allow them to more easily hunt/gather the food that they need to survive. For example, grizzly bears and sea otters both eat fish as their main diet and therefore have both developed canine teeth, while rabbit teeth are different due to them only eating vegetation.

Answer:

A frameshift mutation.

Explanation:

A frameshift mutation is when one adds an extra nucleotide to a series of nucleotides. This will mess up the order of the nucleotide, thus when it forms the codons, and eventually, the amino acids; all of the codons are wrong, thus all of the amino acids are wrong.

In this situation, an extra nucleotide is added to a sequence of DNA, this results in all of the other nucleotides getting pushed over by (1). Thus, all of the nucleotides form the wrong codons and the wrong amino acids. Therefore, a frameshift mutation has occured.
