Answer:

true

Explanation:

The fatty acid chains are the uncharged, nonpolar tails, which are hydrophobic. Since the tails are hydrophobic, they face the inside, away from the water and meet in the inner region of the membrane.

The statement "the tail portion of the phospholipid molecule is hydrophobic" is definitely true.

Phospholipid may be defined as an amphipathic molecule that is constructed from four components. They are fatty acid, a platform to which fatty acids are attached, a phosphate, and an alcohol attached to the phosphate.

The molecule of phospholipid has a polar head and a non-polar tail. The polar head is known as hydrophilic and a non-polar tail is known as hydrophobic.

Such types of tails move away with water, hence they are significantly found at the inner side of the membrane and form a type of barrier.

These tails of phospholipids are typically uncharged which expel water and separates the internal contents of the cell from its outer environment.  

Therefore, the statement "the tail portion of the phospholipid molecule is hydrophobic" is definitely true.

A magnetic storm is a period of rapid magnetic field variation. It can last from ... When these events occur, we can experience a truly large magnetic storm

Explanation:

The event that should be resulted by the magnetic force is the needle of a compass points toward Earth's North Pole.

It is treated like the attraction or the repulsion that should occur between the particles that are electrically charged due to its motion.

It is termed as the basic force that should be held responsible for the impacts like action related to the electric motors and the iron magnets for the attraction purpose.

Answer:

Both parents

Explanation:

Punnett squares will show that for each trait (eye color, hair color, hair type, etc.) there are at least 3 different options (for a 2x2 Punnett square). I've also seen 4x4 Punnett squares where two traits are used.

The mother actually gives more DNA to a baby more than the father because of the little organelles, aka the mitochondria that live inside your cells are only to be received from your mother.

But in DNA, it can vary who's side you can get more of, and in some rare cases, equally. This is because dominant genes carry out around 75% of the time and genes that are recessive can carry out 25% of the time, depending on the genetics of both the mother and the father. Example, brown eyes are a dominant gene over blue eyes, so there is a 75% chance that the baby will have brown eyes and a 25% chance that the baby has blue eyes if one parent has the brown eye gene and one has the blue eye gene.

B - by comparing DNA from the blood cells with DNA from suspects!

Explanation:

DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation.

A DNA sample taken from a crime scene is compared with a DNA sample from a suspect.

If the two DNA profiles are a match, then the evidence came from that suspect. (from www.genome.gov )

Hope this helps! :]

A forensics expert has obtained a sample of human blood from a crime scene, DNA fingerprinting may be useful by comparing DNA from the blood cells with DNA from suspects, which is option B.

DNA fingerprinting is a technique used to identify individuals based on their unique DNA profiles, and by analyzing the sequence of nucleotides in an individual's DNA, forensic scientists can create a DNA profile that is unique to that individual. So to identify the person who left the blood at the crime scene, forensic scientists would analyze the DNA in the blood sample and create a DNA profile, and then find out the criminal based on the DNA fingerprinting.

Hence, DNA fingerprinting may be useful by comparing DNA from the blood cells with DNA from suspects, which is option B.

Explanation:

The fossil record certainly has gaps, mostly because the conditions required to create fossils have been rare ever since life began on Earth. A very small percentage of animals that have lived and died ever became fossils. Thus, many pieces of the puzzle are missing; some will never be found.

Answer:

B

Explanation:

It is less than 1.4 million years old

Based on the absolute dating of the rock layers in this photograph, a scientist could conclude about a fossil found in area A is that it is less than 1.4 million years old.

Fossils may be defined as the dead and organic remains of the past organisms which are preserved deep in the soil over a long period ago.

The fossil found in area A is very recent from the evolution point of view. The deeper the layer, the oldest is the fossil.

Area A of the fossil is synthesized after the time period of 1.4 million years ago, hence the fossil present in that area would be less than 1.4 million years old.

Therefore, based on the absolute dating of the rock layers in this photograph, a scientist could conclude about a fossil found in area A is that it is less than 1.4 million years old.

We use different radioactive isotopes to determine timescale because decay within the rocks according to their half-life rates, and by selecting the appropriate minerals and measuring the relative amounts of parent and daughter isotopes in them, the date at which the rock crystallized can be determined.

First, I read that so incorrectly. Awkward.

An organism's environment affects its physical and self traits by making them adapt. Charles Darwin had discovered this theory with the finches. Places that were harder to get food would make these finches physical change over evolution to help them survive. It changes the animals habits depending on their resources. If a bird eats berries but there is no berries then the bird will have to change its diet or it will die.

It is the food chain going down to envole.

Answer:

what is a food chain?

Food chain, in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism

seaweeds -----> crabs ------>herons

step-1: A food chain always starts with a producer This is an organism that makes its own food Most food chains start with a green plant because plants can make their food by photosynthesis

step-2: Second step of a food chain always starts with a omnivore or herbivore  

herbivores

A herbivore is an animal that gets its energy from eating plants and only plants. Omnivores can also eat parts of plants but generally only the fruits and vegetables produced by fruit bearing plants

omnivores

An omnivore is an animal that has the ability to eat and survive on both plant and animal

step-3: Third step of food chain carnivores or omnivores

carnivore

carnivore meaning "meat eater is an animal whose food and energy requirements derive solely from animal tissue or meat

omnivores

An omnivore is an animal that has the ability to eat and survive on both plant and animal
