Describe the similarities you observe between the major stages in the life cycles of flowering plants and non-flowering, seed-bearing plants.
Answer:
Seeds are found in both flowering and non-flowering plants. Both plants reproduce, the difference being that the former reproduces through blossoms, whereas the latter reproduces through seeds or spores. Because both flowering and non-flowering plants have chlorophyll, they can both photosynthesise.

What are the two causes of variation?
A. Inherited factors and diet.
B. Inherited and genetic factors.
C. Inherited and environmental factors.
D. Habitat and diet.
Answer:
the answer is b
Explanation:
The two main causes of variation are inherited and genetic factors
Students model codominance in fish. B is the allele for blue coloring, and R is the allele for red coloring. They draw three fish with different-colored scales and fins. Their drawings are shown in the table.
Select the boxes to show the genotypes for each fish shown.
The phenotype of the fish when both R and Bl are present will be Blue and Red while the genotype will be BR.
What is co-dominance?Co-dominance in genetics is the condition in which alleles of a gene are both dominant in that when both are present in an organism, the organism will show the phenotype of both alleles.
Since the alleles B for blue coloring, and R for red coloring are both dominant, when both are present in the fish, the phenotypic coloring in the fish will be blue and red.

What does DNA use to store information
DNA stores biological information in sequences of four bases of nucleic acid — adenine (A), thymine (T), cytosine (C) and guanine (G) — which are strung along ribbons of sugar- phosphate molecules in the shape of a double helix.
1. Name the two processes that occur in meiosis that increase genetic variation
The two factors are: crossing-over and independent assortment. Crossing over: In Prophase I of Meiosis I, homologous chromosomes line up their chromatids and “cross-over”, or exchange corresponding segments of DNA with each other. This produces genetic variation by allowing more combinations of genes to be produced.

How do muscles work together to created movement
Answer
Basically they contract and then relax in different places back and forth.
Explanation:
When you move your arm for example, parts of that muscle are stretched while other parts become more relaxed to allow for the tension on certain parts. Basically when one part is stretched, the other part is relaxed, so they're always working together.

Explanation:
Outline seven soil pollutants and state two effects of each of this seven soil pollutants.
[tex]\bold{\huge{\underline{ Answer }}}[/tex]
Soil pollutants are substances which contaminates the soil. Soil pollutants are very harmful substances ,they makes the soil toxic . The presence of these substances in higher concentration directly affects the ecosystem, earth etc.
Here are some major soil pollutants :-1) Industrial wastes
Industrial wastes are the common soil pollutants. The discharge of industrial waste in the soil makes it very toxic and directly affects the growth of plants (agriculture) .Industrial waste also affects the life of some organisms like earth worms which makes the soil more fertile.2) Pesticides
Pesticides are the substances which are generally used to kill the pestes. It includes Insecticides, herbicides and fungicides. The higher concentration of pesticides in cropfield directly affects the human health and responsible for soil pollution, water pollution etc.3) Hydrocarbons
Hydrocarbons are the substances which are composed of hydrogen and carbon. Only some hydrocarbons are responsible for soil pollution as they are very harmful for living organisms. for example the most harmful hydrocarbons is PAHs ( Polycyclic aromatic hydrocarbons) .PAHs in soil affects the growth of plants and it is indirectly responsible for the cancer in humans.4) Metals
Most of the people don't know that the higher concentration of some metals makes the soil very toxic . The concentration of these metals in soil directly kills the human beings and other living organisms.5) Non - biodegradable substances
Most people throw the trash in the soil even they know that soil can't degrade the non - biodegradable substances. When these non - biodegradable wastes eaten by street animals it directly affects the health of those animals and disturbs the ecosystem.6) Human activities
Some people really don't care about the environment. They always do ,what they want to do without even thinking about its consequences on the environment. They throw Cigrattes in the soil, Drop alcohol in soil .These activities makes the soil toxic and the crops that are grown in contaminated soil directly affects the human health.7) Acid rain
It is major reason for the contamination of soil. Some people thought that, It is the natural cause of soil pollution but that's not the reality. Humans are the one's who are responsible for acid rain. Contamination of these acids makes the soil very toxic that it kills the plants on the spot.Answer:
See below.
Explanation:
1) Plastic / Glass:
● Non biodegradable substances & takes a long time to decompose.
● Harmful substances are released into the soil.
2) Acid rain:
● Changes the acid level of the soil.
● Causes harm to the plants, insects & ground water.
3) Pesticides / Insecticides / Artificial fertilisers:
● Alters the health of the soil.
● Causes harm to the plants & the organisms living in the soil.
4) Heavy metals (merculy, arsenic etc.)
● Causes toxic harm to plants & animals.
● Highly poisonous .
5) Industrial wastes:
● pH level of the soil can be altered.
● Makes ground water either too acidic or too basic.
6) Radon:
● Harms microorganisms .
● Can cause lung diseases.
7) Hydrocarbons:
● Affects soil health
● Affects the micoorganisms in the soil.

of translation happens when the ribosome hits a stop codon on the mRNA. 2. of translation always happens at the start codon of the mRNA. 3. The process, performed by the ribosome, of reading mRNA and synthesizing a protein is called . 4. The RNA that has an amino acid attached to it, and that binds to the codon on the mRNA, is called a . 5. Amino acids are attached to tRNA by enzymes called .
We can confirm that when a ribosome hits a stop codon, the translation process halts, which is the process by which the mRNA is read to produce a protein through the use of tRNA and aminoacyl-tRNA synthetase.
What are the distinct types of RNA?The process of translation in order to produce a protein has many parts. The mRNA is the messenger RNA that holds the genetic code needed to create the protein, this is read by the ribosomes. These ribosomes use the aminoacyl-tRNA synthetase enzyme to attach the corresponding amino acids to the transfer RNA or tRNA and later to the protein itself.
Therefore, we can confirm that when a ribosome hits a stop codon, the translation process halts, which is the process by which the mRNA is read to produce a protein through the use of tRNA and aminoacyl-tRNA synthetase.

Examine the words,
impulse, presynaptic cell, neurotransmitters, receptors, postsynaptic cell,
What idea can be described using all the words listed?
The synapse is the place where the electrical impulse is modulated, it begins with a chemical-electric discharge in the presynaptic cell and the postsynaptic cell has the receptors that receive and are activated by the neurotransmitter.
What is synapse?It is the functional relationship of contact between the endings of nerve cells.
This communicative process between neurons begins with a chemical-electric discharge in the membrane of the emitting cell (presynaptic cell).
When said nerve impulse reaches the end of the axon, the neuron secretes a substance that lodges in the synaptic space between this transmitting neuron and the receiving neuron (postsynaptic cell), in turn, this neurotransmitter is responsible for exciting another neuron.
Therefore, we can conclude that the synapse is the place where the electrical impulse is modulated, it begins with a chemical-electric discharge in the presynaptic cell and the postsynaptic cell has the receptors that receive and are activated by the neurotransmitter.
