What is the process in genetic expression?
Answer:
Explanation:
Gene expression is the process by which the instructions in our DNA are converted into a functional product, such as a protein. It acts as both an on/off switch to control when proteins are made and also a volume control that increases or decreases the amount of proteins made.
external structure of Amoeba
Answer:
Structure of amoeba primarily encompasses 3 parts – the cytoplasm, plasma membrane and the nucleus. The cytoplasm can be differentiated into 2 layers – the outer ectoplasm and the inner endoplasm. The plasma membrane is a very thin, double-layered membrane composed of protein and lipid molecules.

Briefly explain what happens during Meosis 1.
Answer:
Explanation:
During meiosis one cell, divides twice to form four daughter cells. These four daughter cells only have half the number of chromosomes of the parent cell. they are haploid. Meiosis produces our sex cells or gametes. (eggs in females and sperm in males)
Chemosynthesis _______. Question 11 options: uses energy derived from hydrocarbons and hydrogen sulfide in place of solar energy produces carbohydrates and sugars occurs around hydrothermal vents near the oceanic ridge system Both a and c are correct. All of the above are correct.
Answer:
The answer is all of the above are correct.
Explanation:
Chemosynthesis occurs in bacteria and other organisms and involves the use of energy released by inorganic chemical reactions to produce food. All chemosynthetic organisms use energy released by chemical reactions to make a sugar, but different species use different pathways. For example, at hydrothermal vents, bacteria oxidize hydrogen sulfide and add carbon dioxide and oxygen to produce sugar, sulfur, and water:
CO2 + 4H2S + O2 ⇒ CH20 + 4S + 3H2O.
Chemosynthesis is the process by which food (glucose) is made by bacteria using chemicals as the energy source, rather than sunlight. Chemosynthesis occurs around hydrothermal vents and methane seeps in the deep sea where sunlight is absent. During chemosynthesis, bacteria living on the seafloor or within animals use energy stored in the chemical bonds of hydrogen sulfide and methane to make glucose from water and carbon dioxide (dissolved in seawater). Pure sulfur and sulfur compounds are produced as by-products.

9. UGU-UUC-CCU-UAA
UGU-UCC-CUU-AA
Answer:
7. Substitution mutation
8. Substitution mutation
9. Frameshift mutation
Explanation:
A substitution mutation is any kind of mutation that involves replacement of one or more nucleotide base by another in a sequence.
A frameshift mutation, on the other hand, is a mutation that changes the reading frame of the sequence. Two types of mutations cause frameshift viz: insertion and deletion mutation.
In the following sequences, mutation has occured as follows:
7. UGU-CCG-GAA-CGA to UGC-CGG-GAA-CGA - Substitution mutation has occured because nucleotides C and G has replaced C and U in the first and second codons respectively.
8. GAA-CGU-AGC-GGU to GAU-CGU-AGC-GGU- A substitution mutation because nucleotide U has replaced A in the first codon.
9. UGU-UUC-CCU-UAA to UGU-UCC-CUU-AA - A frameshift mutation because nucleotide U has been removed from the second codon, hence, causing a change in the reading frame.

How do I make a Punnet Square without knowing if traits are Dominant or Recessive? I cannot refer to the parents of the current generation, so I have to rely on that generation to create a theoretical next generation.
If you are referring to a previous generation, that would probably mean that the traits they have are the dominant ones
Explanation:
if you know all the traits possible, then the ones the parents have of a previous generation are most likely the dominant ones, from there, you can hopefully figure out another generation. could you attach a picture if this didn't help? thanks
In this assignment, you will expand your knowledge of muscle structure and function by exploring muscle strength and contraction. Then, you will use what you learn to answer some follow-up questions.
Read the article and use the information to answer the following questions.
Strongest Muscle
Name the four ways muscle strength can be measured and briefly describe each.
Answer:
Absolute strength measures maximum force.
Dynamic strength measures repeated motions.
Elastic strength measures exertion of force rapidly.
Strength endurance measures fatigue resistance.
Explanation:
im megaminds child
Absolute strength measures maximum force. Dynamic strength measures repeated motions. Elastic strength measures exertion of force rapidly. and Strength endurance measures fatigue resistance.
What is Muscle strength ?Physical strength and muscular endurance share some characteristics, they also differ significantly. Your ability to apply force or lift weights is a measure of your muscular strength. Using heavier weights for fewer repetitions helps develop muscular strength.
The term "muscular endurance" describes a muscle's capacity to endure prolonged periods of repeated contractions against opposition.
Long-distance running, cycling, or swimming, as well as bodyweight exercises and circuit training, are exercises that increase muscle endurance.

If the gene sequence of DNA is A T T C G A C T C G what will the complementary mRNA sequence be that is made during transcription?
Answer:
U A A G C U G A G C
Explanation:
The complementary bases in RNA are the same as DNA with G-C (guanine to cytosine).
But, they are different in that RNA has A-U (adenine to uracil) instead of A-T (adenine to thymine).
Using these RNA base pairs of G-C and A-U, create the complementary mRNA sequence:
A T T C G A C T C G
Translate:
U A A G C U G A G C
So, the complementary mRNA sequence will be U A A G C U G A G C

why are living organisms classified?
Answer: See explanation
Explanation:
An organism refers to a living thing which can react to stimuli, move, grow, has an organized structure, reproduce, and can adapt.
Living organisms can be classified into kingdom, phylum, classes etc. The reason the classification of living organisms include:
1. Gives information about diversity of living organisms.
2. Easy identification of the organisms
3. Shows inter-relationship among the organisms.
4. Helps in understanding the evolution of the living organisms.
living organisms are classified so that it becomes easier for us to examine or study organisms
Please help me with this! *30 *points Picture included
Answer:
1.) The first picture is mitochondria and the second picture is chloroplast
2.) The second one is only in plants
3.) The first one is found more commonly in animal cells
4.) Glucose & oxygen goes into #1 and releases ATP energy and water & carbon dioxide (waste) during cellular respiration
5.) Sunlight and water goes into #2 and releases oxygen (waste)
6.) The waste product from mitochondria is what the chloroplast needs to perform photosynthesis and vice versa for mitochondria where the waste product from the chloroplast is what mitochondria needs to make ATP energy
7.) They both have folds and membranes because this is how energy is transferred from one place to another.

Hippopotamuses live in Africa’s rivers and lakes. They’re herbivores and coexist with other herbivores and carnivores. Which action could lead to a decrease in the number of hippos?
Answer:
If any of the other carnivores are predator they might eat the hippos. If the other herbivores population incresses there food supply may drop. If there is a drought there habitat will be in danger. Pouchers are also a threat to this animal.
Explanation:
In maize, yellow kernel color is dominant to white, and wrinkled kernel shape is dominant to the smooth form. Considering both of these traits jointly in self- fertilized dihybrids, the progeny appeared in the following numbers: 193 white, genes assort independently? Support your conclusion using appropriate statistical analysis. wrinkled; 184 yellow smooth; 556 yellow, wrinkled: 61 white smooth
Answer:
yellow, wrinkled are high in population whereas white smooth is lower in population.
Explanation:
Due to self-fertilized dihybrids, the offspring are yellow wrinkled, hybrid and white smooth. 556 yellow, wrinkled are high in population because of the dominant allele while on the other hand, 61 white smooth are obtained and less in number due to recessive nature that comes very little in the population. 184 yellow smooth and 193 white, wrinkled are the hybrid offspring that has both different characteristics from their parents.
