Mineral ions are required in the human diet in small quantities. State the mineral ion required for each process: a) making bone b) making haemoglobin
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".

DNA is responsible for making a cell¨s what?
Answer:
The answer is in the explanation bellow
Explanation:
the major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code. To read the genetic code, cells make a copy of a stretch of DNA in the nucleic acid RNA.
Describe the energy transformations that exist on earth and in your daily life. Describe at least 3 factors and why each one is important. 40 POINTS
Answer:
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.
An electric fan transforms electrical energy into kinetic energy.

Description of a ladybugs metamorphosis, including whether it is complete or incomplete
Complete metamorphosis has 4 stages: egg, larva, pupa, and adult. The larva and pupa stages look very different from the adult stage. Examples include butterflies, beetles (including ladybugs), and mealworms. Incomplete metamorphosis has 3 stages: egg, nymph, and adult..
Why does asexual reproduction result in offspring with identical genetic variation? Use the examples that you studied earlier in this lesson to support your answer.
Answer:
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.

Explanation:
Grazing is a method of feeding in which herbivores, such as sheep, feed on plants. The intensity in which the herbivores in an ecosystem graze impacts the biodiversity of the plants in that ecosystem, as shown in the graph below.
According to the graph, biodiversity is low during low grazing intensities. This is because only a few species of plants are able to outcompete the others and dominate the ecosystem. As the grazing intensity increases, the biodiversity increases because the dominant plant species are kept in check by the grazers. This allows the weaker competitors to grow. At very high grazing intensities the biodiversity decreases because only plants with adaptations to tolerate the effects of grazing are able to survive.
Which of the following best explains how plant biodiversity would change if all of the grazers were suddenly removed from an ecosystem experiencing high intensity grazing?
A.
Plant biodiversity would likely decrease because every species of plant could grow without limitation after the herbivores were removed.
B.
Plant biodiversity would likely increase because removing one population from an ecosystem would allow more resources for all the others.
C.
Plant biodiversity would likely decrease because a few of the more dominant plant species would outcompete all the others.
D.
Plant biodiversity would likely increase because only a few of the remaining plant species would be able to thrive without the herbivores.
Answer:
I believe the answer is B , it should be .
Explanation:
Answer:
Plant biodiversity would likely decrease because a few of the more dominant plant species would outcompete all the others.
Explanation:
The base pairing rule for DNA is adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C).
When RNA copies the DNA, the base pair for adenine changes to _______ instead of thymine.
Question 5 options:
Thymine
Uracil
There is no new base
U.. Something Or Another...
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.
Answer:
Uracil

how would you describe what the cells of each stage of the cycle look like ? what are the visible features of the cells.
Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis
Interphase:
Is known as the resting stage. Replication of DNA occurs.
- G1
-S
-G2
Prophase:
The chromosomes are visible, centrioles are formed and begin to move to opposite sides. This is where you see the dissolving of the nuclear membrane.
Metaphase:
The chromosomes line up in the centre of the cell.
Anaphase:
This when the cell divides (should look like two circles splitting) you will see the spindles begin to shorten which pull chromatids apart.
Telophase:
The nuclear membrane is reformed.
Hope this helps (:

Describe the amount of sunlight at the poled and at the equator throughout various times of the year. Why does this occur?
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.

Which of the following statements about oceans is incorrect?
A) Oceans collect water from other reservoirs including streams and rivers.
B) Oceans are the main source of drinking water on Earth's surface.
C) Oceans are connected to other reservoirs through evaporation and precipitation.
D) Oceans are the main type of reservoir that contain salt water.
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.
What do plants do with light energy during photosynthesis?
Answer:
during photosynthesis light energy is captured and used to covert water, carbon dioxide and minerals into oxygen
Explanation:
Answer:
Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Explain how similar and different sexual reproduction in plants and animals is?
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.
