25POINTS HELP!!!!!!!!!!!!!!!!!!!

Answer:

a) making bone - Calcium

b) making hemoglobin​ - Iron

Explanation:

Mineral ions are defined as the charged forms of minerals which are required in small amount in human body but are essential otherwise leads to deficiency symptoms.

Making bone and making hemoglobin​ both require mineral ion. Making bone require calcium ion, as it maintain the bone mass and strengthen the bones. hemoglobin​ formation require iron ion, as iron helps to oxygenate our blood cells.

Hence, the correct answer is "a) making bone - Calcium

b) making hemoglobin​ - Iron".

Answer:

Uracil

Explanation:

DNA molecule is made up of monomeric nucleotides, which are of four different types viz: Adenine, Guanine, Cytosine, and Thymine. According to the COMPLEMENTARY BASE PAIRING RULE as proposed by Chargaff, these nucleotides pair in the DNA as follows: Adenine to Thymine (A-T), Guanine to Cytosine (G-C).

However, in the RNA molecule (second nucleic acid), a fifth nucleotide called URACIL is found. This URACIL replaces thymine because thymine is only found in DNA while Uracil is only found in RNA. When DNA is transcribed into mRNA, Adenine nucleotide gets transcribed into Uracil in the RNA instead of thymine i.e A to U.

All the organism that performs cellular respiration is Oxygen is required for cellular respiration and is used to break down nutrients, like sugar, to generate ATP (energy) and carbon dioxide and water (waste). Organisms from all kingdoms of life, including bacteria, archaea, plants, protists, animals, and fungi, can use cellular respiration.

Answer:

A dye needs to be added to the gel electrophoresis

Explanation:

Ethidium bromide (EtBr) is a reagent that adheres to DNA and fluoresces under ultraviolet (UV) light. Due to this feature, EtBr is widely used to dye DNA strands in molecular biology techniques such as agarose gel electrophoresis. The most common dyes for visualizing and staining nucleic acids during gel electrophoresis include EtBr, SYBR gold, Eva green and SYBR safe. If EtBr (or any other staining agent) was not added to the electrophoresis gel and/or running buffer, the gel will be dark under UV light (even the ladder lane will look empty) because DNA has not been stained.

The mistake the student made was by not adding dye to the sample. Dyes

are commonly used during electrophoresis.

Agarose gel electrophoresis is the process which helps in the separation

and purification of DNA samples. This process involves the use of dyes

which acts as markers.

in this scenario, we were told no DNA bands show up and the marker lane is

clear means no dye was added.  The common dye used in agarose gel

electrophoresis is Ethidium bromide (EtBr) which should be added by the

student.

Answer:

Neither of the poles are tilted towards the sun. Hence, the sun rays fall directly on the equator due to which all the places on the Earth experience equal daylight hours and equal night time hours that is, 12 hours of day and 12 hours of night on all the places of the Earth.

Answer:

The fact that the equatorial Sun is always so close to the zenith at solar noon explains why the tropical zone contains the warmest regions on the planet overall. Additionally, the Equator sees the shortest sunrise or sunset because the Sun's path across the sky is so nearly perpendicular to the horizon.

Energy is the fundamental need of our everyday life. ... This means that we can convert electrical energy into heat energy and light energy, solar energy can be converted to chemical energy, potential energy can be converted into kinetic energy, Gravitational potential energy can be converted into kinetic energy etc.

Explanation:

The Sun transforms nuclear energy into heat and light energy.

Our bodies convert chemical energy in our food into mechanical energy for us to move.

The reason asexual reproduction results in identical offspring is because the DNA is replicated exactly from the parent to the daughter. One example is bacteria.

Explanation:

Answer:

Sexual reproduction results in offspring  with genetic variation due to the multiplication brings about limitless prospects of hereditary variety. The examples, that can be studied to support this would be at the end of the day, sexual generation brings about posterity that are hereditarily extraordinary. They vary from the two guardians and furthermore from one another. This happens for various reasons.

Plant's reproduce via. pollen or seeds, whilst the animals reproduce by, and I quote, "getting on top of each other to have a fun time". Hope that helped

Answer:

Both plants and animals reproduce sexually, producing a male and female gamete, which fuse to form a zygote. However, plants are also able to reproduce asexually, unlike most animals. In sexual reproduction in animals, the two gametes are the spermatozoa and the oocyte, which when fused become the ovum.

Explanation:

Answer: C

Explanation:

It made sense.

Answer:

B

Explanation:

B is incorrect because oceans are not the main source of drinking water. They contain the most water, but the ocean is not drinkable as it is much too salty and would lead to dehydration and the shriveling up of cells, causing death if it was the only water you drank. Usually only small island countries will have to resort to drinking ocean water after desalinating it, but most of the world gets their water from other sources such as groundwater, springs, lakes, and rivers.
