Answer:
During the process of the type of cloning known as Somatic Cell Nuclear Transfer (SCNT), once the nucleus is removed from the egg cell, blunt and sharp pipette both are used. The purpose of the blunt pipette is to hold the egg cell in position whereas the sharp pipette penetrates the cell to take the nucleus out by sucking it - a process known as "enucleation". This nucleus is discarded. Rather, this nucleus is replaced by a nucleus taken out from a somatic cell (same way as described before) of the same organism.

why do animals and plants need nitrogen
Answer:
They need Nitrogen to make Amino acid, DNA but the nitrogen in the atmosphere can't be used directly. Some nitrogen fixing bacteria fix it then it is able to use for plants and animals.

What is currently happening with Mount Etna?
Answer:
As Italy’s National Institute of Geophysics and Volcanology (INGV) explains on a recent blog post, the nascent eruption began on the night of May 29. Starting off by producing a thick column of ash rising from the New Southeast Crater, it gave way on May 30 to a far more lava-heavy display in the area, featuring two fissures blenching out lava.
Answer:
There is currently no eruptive activity at the volcano involving fresh lava and monitoring signals do not suggest an immediate change likely; only a weak thermal anomaly continues to be present from the southeast crater complex.

I believe this question is trying to get you to realize the difference between acquired traits(one you get through doing something during life) and heritable traits(ones from Mom/Dad). For example, I really wish I was 6 foot 4... but the height trait comes genetically from your parents since it is coded in my DNA how tall I will be, therefore this trait must be passed down genetically and somewhere down the evolutionary tree the humans in the region which my family comes from was better off being short. An example that comes from acquired traits could be muscularity... my parents are both not very muscular but throughout my lifetime I enjoy working out and have become much more muscular, no matter how much your parents or grandparents lift weights YOU won't change so that change must be acquired through aging during your lifetime. Now the amount of muscle your body can put on is a heritable thing but that is beside the point. Hope this helps :)

Answer: Sperm Whale
Explanation:
They found that the DNA sequence of the sperm whale and pygmy sperm whale were more closely related to the baleen whales than to other toothed whales and dolphins. The study also showed that the beaked whale (which has only a few teeth) is only distantly related to any other whale or dolphin. Stated in science article by Koen De Smet. Not plagarized.

Which of these is an example of genetic modification:
a. Mapping the genome of the giant squid
b. Comparing the genes of children to their parents
c. Getting a flu shot
d. Adding a gene for mold resistance to corn DNA
Answer
D, genetic modification is a technique to change the characteristics of a plant, animal or micro-organism by transferring a piece of DNA from one organism to a different organism.
Explanation:
(mark as brainliest please)
Changes in genetic data lead to gene modification. Adding a gene for mold resistance to corn DNA is an example of genetic modification. option D is the correct answer.
What is genetic modification?
Genetic modification is a process in which the genes of an organism are modified. This can be done by base insertion or deletion or by any other environmental factor. Genetic modification can be done artificially. CRISPR-Cas9, gene editing, etc. are some examples.
This is done to get more productivity in crops, to reverse a genetic disease, etc. An example is adding a gene for mold resistance to corn DNA. Due to this gene modification, the corn will produce some proteins that will protect it from mold attack. Other options are not correct for the statement, as there is no change in gene activity.
Hence, the correct option is to add a gene for mold resistance to the corn. Option D is the correct answer.

Liam knew that all living things have common characteristics. His new baby brother made him think about how different all the types of living things were. Which of the following is not a common characteristic shared by all living things?
A. made of a cell or cells
B. made of similar chemicals
C. respond to surroundings
D. spontaneously generate
Answer:
Option D) - Spontaneously generate.
Answer:
Spontaneously generate
Explanation:
all living things have cells, are similar chemically (like have water) and respond to surroundings.
Spontaneous generation refers to an obsolete body of thought on the ordinary formation of living organisms without descent from similar organisms. The theory of spontaneous generation held that living creatures could arise from nonliving matter and that such processes were commonplace and regular.
What is the cause of Angelman Syndrome?
a) A mutation that occurs randomly after birth or due to a viral infection in the mother during pregnancy.
b) The shutting off of the paternal chromosome and the deletion on Chromosome 15 from the mother.
c) The shutting off of the maternal chromosome and the deletion on Chromosome 15 from the father.
d) A large deletion of chromosome 15 that is inherited from each parent.
Answer:
Angelman syndrome is caused by a genetic mutation on chromosome 15.
Explanation:
Angelman syndrome is caused by a genetic mutation on chromosome 15. The name of this gene is UBE3A. Normally, people inherit one copy of the gene from each parent, and both copies become active in many areas in the body. Angelman syndrome occurs when only one copy of the gene is active in certain areas of the brain.
According to “Past Climate Changes on Earth,” what changes to the atmosphere caused temperatures to increase, making the Eocene such a warm time in Earth’s history?
Answer:
The most important factor was the accumulation of greenhouse gases, especially methane and carbon dioxide.
Explanation:
The Eocene climate began with warming climate at 56 million years ago (Mya) and finalized at around 49 Mya ago. It is believed that during this period the greenhouse gases increased the temperature on the Earth's surface. This hypothesis is supported by evidence that indicates the melting of the ice cap in the poles.

Which statement best describes Mendel's law of dominance?
O
A. Each parent of an offspring contributes two factors for each of the
offspring's traits.
B. The separation of two factors for one trait will always affect the
separation of another trait's factors.
O
C. Inherited traits are controlled by two factors that separate during
reproduction.
D. Only one of the two factors that control a trait is expressed when
both types of factors are present.
Only one of the two factors that control a trait is expressed when both types of factors are present best describes Mendel's law of dominance. Thus option D is correct.
what is Mendel's law?
According to Mendel’s Law of Dominance When an organism is mixture of heterogeneous trait, it expresses allele which are dominant, here the dominant trait always masks the recessive trait.
The trait is present in the form of two allele and one allele is dominant over the other allele which is recessive.
The dominant allele contributes exclusively to the phenotype of the offspring and Dominance can also be described as when one of the two alleles is non-functional means it does not produce a functional protein.
The recessive trait will be expressed only when both the allele are present in homozygous form from both parents.
Thus option D is correct.

What do you mean by the Excretory system?
The excretory system may be defined as the system that consists of a pair of kidneys, ureters, and urinary bladder. It removes wastes from the body.
Excreting waste materials, maintaining pH balance, maintaining body temperature, maintaining salt balance, maintaining hormone levels (aldosterone), and maintaining water balance are all the functions that are performed by the excretory system.
Therefore, only excreting blood is the function that is not performed by the excretory system.
