If an H is for tall trait which is dominant and h is the recessive trait for short,
which of the following crosses will result in 1:1 tall:short progeny (offspring).

A) HH Xhh
B) hh X hh
C) Hh X hh
D) Hh X Hh

Answers

Answer:

The cross that guarantees a height trait ratio in the offspring of 1 : 1 high/low is Hh X hh (option C).

Explanation:

For a characteristic such as size, where tall (H) is the dominant trait and short (h) is the recessive, the crossing of a tall heterozygous (Hh) individual with a short one will have a probability that half of the offspring will be tall and the other half short.

This can be demonstrated with a Punnett square:

Cross Hh X hh

Alleles      H      h

h              Hh    hh

h              Hh    hh

Based on this result, half of the offspring will be tall, with genotype Hh, and the other half short, with genotype hh, which corresponds to a tall : short ratio of 1 : 1.

In the other options is not possible to obtain this result:

A) HH Xhh  = 100% Hh.

B) hh X hh  =  100% hh.

D) Hh X Hh = 50% Hh, 25% HH and 25% hh.

what determines how far south the cold air from the north pole travels

Answers

Answer:

Please mark as Brainliest.

Explanation:

Polar easterlies are the cold and dry wind that blows from the polar regions (North pole and South pole) to the region of 60 degrees latitude. This type of wind is formed due to the sinking of the cold air resulting in the formation of a high pressure zone at both the poles. This wind when blows from the poles to the 60 degrees latitude, it slightly gets deviated towards the western side because of the effect of the Coriolis force. This Coriolis force comes into the picture due to the earth's continuous rotation.

Thus, the polar easterlies determines how far south the cold air travels from the North Pole.

What would happen if the mitochondria were missing from a cell?

Answers

Answer:

We'd be in big trouble...

Explanation:

The mitochondria is the powerhouse of the cell, without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration.

The absence of mitochondria would have a profound effect on cellular function, including the cell's ability to produce energy, regulate ROS levels, and control important signaling and metabolic pathways. Such a cell would likely be unable to survive for very long.

What is the effect of mitochondrial removal?

Without mitochondria, the cell would not be able to generate ATP through aerobic respiration, which takes place in the mitochondria. Instead, the cell would have to rely on other, less efficient metabolic pathways to produce energy. Mitochondria are also important for regulating the levels of reactive oxygen species (ROS) in the cell. Without mitochondria, the levels of ROS would likely increase, leading to oxidative damage to the cell's proteins, lipids, and DNA. Mitochondria play important roles in cell signaling pathways, including those involved in apoptosis (programmed cell death) and calcium signaling. Without mitochondria, these pathways would likely be altered, which could have profound effects on cellular function and survival.

Hence, such a cell would likely be unable to survive for very long.

Of the three waves shown, Wave 2 has the greatest
wave speed, because it has more crests than the other ropes
O frequency because it has a large wavelength than the other ropes
wave speed because the rope is moving up and down faster than the other ropes
frequency, because there are more crests in the same length of rope than there are in the other waves

Answers

Answer:

D. frequency, because there are more crests in the same length of rope than there are in the other waves

Explanation:

Wave frequency is defined as the number of waves passing a fixed point at a given time.

Wave frequency is highly influenced by the number of crests in the wave that pass the fixed point in 1 second. It means, more is the number of crests in the same length of rope, the higher will be the wave frequency.

Wave 2 has a maximum number of crests and thus wave 2 has the greatest wave frequency in comparison to other ropes.

Hence, the correct answer is "D".

Answers

Answer:

A. Protection

Explanation:

These plants have this external protection system to protect them against being eaten by these animals.

In cases where these plants are approached to be eaten by these animals, these systems which in this case are these hairs tend to make an effort by discomforting the approaching animals.

The animals upon sensing this discomfort retreat from feasting on these plants which thus prolongs their lives and prevent them from being eaten by these animals

Answer:

Because they are hydrophobic

Explanation:

The image shows a cell membrane, which is made up a phospholipid bilayer. The phospholipid bilayer is made up of a phosphate head, which is hydrophillic, and fatty acid tail, which is hydrophobic. That means they are repelled by water.

Because the tails are hydrophobic, they are repelled by the water towards one another, while the heads remain facing outwards,

What is the question

Earth is 150 million kilometers from the sun, and the solar "wind" travels at about 400 km/sec. How long does it take particles from a solar storm to reach Earth? (Hint: Time = Distance / Speed. To convert from seconds to hours, divide the time in seconds by 3600.)

Answers

Answer:

The correct answer is - 4.34 days.

Explanation:

Given:

Distance from the sun to earth = 150 million kilometer

= 1500,00,000 km

The solar "wind" travels = 400 km/sec

= 400*60*60 km/ hour

= 1440000 km/hour

Then time = distance/speed

time = 1500,00,000 km/1440000 km/hour

time = 104.166666667 hours

time = 104.166666667/24

=  4.34 days.

Large, circular lily pads are able to float on the water's surface.

Answers

Answer:

true

Explanation:

they're buoyancy

The property of water in "Large, circular lily pads are able to float on the water's surface" is cohesion.

What is cohesion?

Cohesion refers to the attraction of one water to another. This force will cause the water in the lake to develop surface tension. The large and thin leaf of the water lily gives it a low force per area.

The leaf will float above the water if the force acting on the surface is not greater than surface tension. The ability of water spiders to walk on the surface tension of the water.

The leaves of lotus float on the water because the bottom of the leaves have edges and thick ribs that capture air between them, which helps them to float on the water.

Thus, the property of water that is shown in the given statement is cohesion.
