The reaction to produce soap can be completed by cooking animal fat with a very strong solution of SODIUM HYDROXIDE.
This process is called saponification. Chemically, animal fat and strong solution of sodium hydroxide or potassium hydroxide mixed together to produce soap and glycerol.

Answer:

With respect to the differences in the DNA sequence of six species, including the human one, it is true that the DNA sequences may vary but the aminoacid sequences are identical.

Explanation:

Options for this question:

The DNA sequences may vary but the amino acid sequences are identical.
The nitrogen bases in the nucleotides must also be different in each.
The process in producing additional DNA, replication, is identical in all six.
The process of producing DNA, or replication, varies due to the differences in the DNA codes.

The different species that exist have specific genomes for each of them, this is the genetic information contained in the DNA varies from one species to another, as can be seen in the scheme (see image). However, the genetic code is universal, and does not vary from one species to another.

The genetic code is found in the RNA molecule and is a sequence of nucleotides that, organized in triplets (codons), are responsible for the synthesis of specific amino acids. An RNA molecule contains the information necessary for protein synthesis.

The scheme shows the differences of five species with respect to the human, based on the respective DNA sequences. But what it does not show is a universally accepted truth, that the nucleotide sequence encoding an amino acid is the same for each of these species.

A body decelerates uniformly to a constant speed and after some time it accelerates uniformly Draw the shape of speed time graph

storchak [24]

Answer:

Kindly check attached picture

Quantity measured is DISTANCE

Explanation:

Segment AB = measures uniform deceleration

BC = Constant speed moved by the car

CD = Uniform acceleration

During uniform deceleration: the speed of the body is reduced at a constant rate with time.

During Constant Speed, the car maintains a Velocity which does not increase or reduce at a certain time interval.

During uniform acceleration the speed of the car increases at a constant rate with time.

B) THE quantity measured by the area covered under a speed-time graph is distance :

With speed on the vertical (y-axis) and time on the horizontal (x-axis)

Area of trapezium = 0.5(AD + BC) × height

What does the plant create in order to reproduce offspring?

mamaluj [8]

Plants either reproduce sexually or asexually, depending on the type of plant. In sexual reproduction, two germ cells, or gametes, fuse to create the beginning of a genetically unique offspring. In asexual reproduction, a plant cell splits in two to create a genetically identical offspring.
