In what way is the genetic code in all organisms the same?
Answer:
All organisms have the same nucleotides
Explanation:
All organisms have DNA. DNA is made up of the nucleotides Guanine, Adenine, Thymine, and Cytosine, with Guanine pairing with Adenine, and Thymine pairing with Cytosine. The combinations of pairs in a sequence determine an organism's individual genes.
What’s the answer to this question
Answer:
D
Explanation:
Crayfish depend upon small invertebrates for survival. If there is a large decrease in the number of small invertebrates, then there aren't enough nutrients to go around, and so crayfish that don't get nutrients will start dying out.

Describe how a rainbow would look if viewed through a blue filter. Explain why the rainbow would appear this way
help please!
answer: all the colours except from blue would appear black as the wavelengths that correspond to these colours have been absorbed by the filter. The blue part of the rainbow would appear blue as the blue light is reflected back into your eyes and not absorbed by the filter.
identify the different forms that water takes as altitude increases. (surface to the upper troposphere)
At sea level water occur in natural liquid form in seas, lakes, rivers, waterfall. Water can be salty or freshwater.
What is troposphere?The layer of the atmosphere closest to the earth is the troposphere. This layer is where weather occurs. It starts at the surface of the earth and extends out to about 4- 12 miles. The temperature of the troposphere decreases with height. This layer is known as the lower atmosphere.
As the altitude increases water changes its form as on the mountains where temperature is very low, exist in snow form. As the more height increases, the water changes into water vapour. In stratosphere water changes into gaseous form called as clouds.

7. Which organism would usually be in the fourth trophic level?
(a) rats
(b) humans
(c) rabbits
(d) hawks
The organism that would be in the fourth trophic level is the hawks. That is option D.
What are trophic levels?Trophic levels are the different feeding positions that are found in a food chain and which shows the movement of energy from one position to another.
The organisms on the fourth level of a food chain are known to consume the secondary consumers.
Therefore, the hawk in an organism of the fourth trophic level because it can eat snakes which are secondary consumers.

how can the process melting and cooling of magma affect the rock cycle
Answer:
Lava eruptions can be “fire fountains” of liquid rock or thick, slow-moving rivers of molten material. Lava cools to form volcanic rock as well as volcanic glass. Magma can also extrude into Earth's atmosphere as part of a violent volcanic explosion. This magma solidifies in the air to form volcanic rock called tephra.

hormones are transported from one part of the body to another
Hormones travel throughout the body, either in the blood stream or in the fluid around cells, looking for target cells. Once hormones find a target cell, they bind with specific protein receptors inside or on the surface of the cell and specifically change the cell's activities.
Explanation:
Hormones are secreted by glands and travel to their target oragan through bloodstream.

A mother has a genotype of IAIA, and a father has a genotype of IBi. Which of the following describes the parents' phenotypes?
Individuals with genotype the IAIA or IAi have blood type A. The ones with IBIB or IBi have blood type B. Others with IAIB have blood type AB, and those with ii have blood type O. Mother has phenotype A and father has phenotype B.
What is genotype?Genotype is the genetic representation of an individual.
A blood genotype indicates the genetic composition of the blood type of an individual.
Blood genotype represents the following phenotype:
IAIA or IAi as blood group AIBIB or IBi as blood group B.IAIB as blood group AB.ii as blood group O.Thus, according to the given scenario, the genotype of mother is IAIA and father is IBi, so the phenotypes will be A and B respectively.

2.2 A learner gives you a rather expensive cycad in a pot for your birthday. The class monitored and documented its growth throughout Term 3. You decided to leave it outside your classroom during the school holidays but found it dead when you returned to school. Explain to your class why this might have happened. (5)
Cycads are an group of vascular plants that are ancient and were prominent components of the world's flora. As the cycad should not be kept dry, leaving it outside the classroom during holiday and not watering properly was the main reason behind the loss of that cycad.
What are the conditions in which a cycad can grow well?Cycads usually prefer warm, moist environments in full sun for survival. As some species are also adapted to dry arid areas, with less winter rainfall.
With respect to the soil, Cycads can tolerate most garden soils with the addition of compost and organic matter, till they are well-watered.
As the cycad was left in the classroom during the school holidays and was not watered and given compost properly, it was found dead.
Thus, watering and composting was the main reason behind the loss of that expensive cycad.
