Answer:
Amoeba engulfs food particles with the help of pseudopodia which are the projections of cell membranes. A food vacuole is then formed around the food particle. Amoeba then secrets digestive enzymes that break down the food particle and digest it.
Explanation:
Answer:
Explanation:
Amoeba obtains its food by the process of endocytosis. It has flexible cell membrane. It engulfs the food particle with the help of pseudopodia and then forms a vacuole around it. When the particle is completely trapped the amoeba secretes digestive enzymes that digests the food.
what term describe Movement of gases across the respiratory membrane in the pulmonary capillaries or into the alveoli?
Answer:
At the respiratory membrane, where the alveolar and capillary walls meet, gases move across the membranes, with oxygen entering the bloodstream and carbon dioxide exiting. It is through this mechanism that blood is oxygenated and carbon dioxide, the waste product of cellular respiration, is removed from the body.

Drag each label to the correct location. Each label can be used more than once. In a hydropower station, water stored in dams is allowed to fall with force to make a turbine move. The turbine moves and produces electricity. In the diagram, identify the stages of transformation of energy in the hydropower station. Please help!!
Answer:
Stored water - gravitational energy
Water fall - kinetic energy
Turbine - kinetic energy
Powerlines - electric energy
Explanation:
Dams are used to store or hold water for hydroelectric power plants. This stored water which has gravitational energy is a form of potential energy.
When the water is left to fall and run fast through the turbine, the gravitational energy is transformed into kinetic energy which makes the turbine to spin.
As the turbine spins, kinetic energy that is produced also powers the shaft of the engine in the electric generator, which produces electricuty.
Kinetic energy is transformed to electric energy and transmitted along powerlines.
*See attachment below for labelled energy that is being transformed at several points.
Answer:
Stored water - gravitational energy
Water fall - kinetic energy
Turbine - kinetic energy
Powerlines - electric energy

Answer:
distal convoluted tubule
Explanation:
This is the region of the nephron downstream the macula densa ,which extends the to convulence of the collecting duct.Due to response to mineralocoticoid aldosterone they can be categorised as Distal Convoluted 1 and Distal convoluted 2. This steroid hormones is responsible for homeostatic control of hyperkalemia.
The DCT cells are simple cuboidal epithelium.The stained or pointed part of the image represented this possess this shape,they are therefore portion of DCT. Besides the stained cells are located above the glomerulus ()in the cortex as indicated,therefore they can not be the proximal which must be below the glomerulus, based on the shape ascending and descending loop of Henle (despite located in the cortex too).
The functions of the DCT is in the absorption and secretions of ions(majorly ca+,Na+ and chloride ions.By secreting hydrogen and reabsorbing HC03 ions ,the pH of the urine is maintained.

when does mutation have the greatest effect; translation, RNA synthesis, DNA Replication or somatic cell formation?
Answer:
It depends on the specific cell type that suffers the mutation. For example, in stem cells, it is reasonable to expect that mutations in the genes involved in DNA replication will have critical consequences
Explanation:
A mutation is a genetic modification in the DNA sequence due to errors during the mechanism of DNA replication or by the effects of environmental (mutagenic) factors. A mutation in the germline can be inherited in the next generations, while a mutation in somatic cells is not inherited. Moreover, a mutation affecting RNA synthesis may have diverse effects depending on the function of the gene involved in this mutation. In a similar mode, a mutation in one gene associated with the mechanism of DNA replication can have critical consequences on the cells originated from the mutated parental cell, but again it is variable and generalizations can not be made without knowledge of the cell type suffering this modification.
Genetic factors determine how susceptible a person is to developing obesity, but __________ factors such as a consistently healthy lifestyle and a healthy diet can play a significant role as well.
a. modulation
b. genomic
c. epigenetic
d. endogenous
Hi there! Hopefully this helps!
--------------------------------------------------------------------------------------
The answer is: A, Modulation.
The non-genetic factors such as eating habits or physical activity which lead to a healthy lifestyle and diet, greatly modulate the particular risk for developing obesity. These modulation factors are thought to possibly interact with the genetic predisposition for obesity through epigenetic mechanisms.
Why is the word "translation" used for protein production? Protein production is the process of:________.
Answer:
Answered below
Explanation:
Translation is the actual process of protein synthesis and it occurs in the cytoplasmic ribosomes. Protein production or protein synthesis is the process in which cells make proteins. This process occurs in two stages called transcription and translation.
Transcription involves the transfer of genetic information in the deoxyribonucleic acid to the messenger ribonucleic acid in the nucleus through the process of initiation, elongation and termination. The messenger ribonucleic acid is processed and carries the information to a ribosome in the cytoplasm where protein production takes place through translation.
During translation, the instructions in the messenger ribonucleic acid are read and transfer ribonucleic acids ensure the correct sequencing of amino acids in the ribosomes. The rRNA is involved in the bonding of the base pairs to produce a polypeptide chain which is a unit of a finished protein.
Answer:
The word translation is use for protein production because it is the process of translating RNA sequence of bases.and thereby producing sequence of encoded amino acids from the RNA
sequence which is a consist of polypeptide chain during protein synthesis.
Protein production is the process of synthesising protein.
Explanation:
Translation is a process that occur in the RIBOSOMES or endoplasmic recticulum after transcription of RNA and it is the process where genetic code in the messenger RNA is decided or translated to a sequence of amino acid.
Protein synthesis is processs by which cells produce protein which occur in the RIBOSOMES.
Protein synthesis occurs in two stages which are Transcription and translation.
Transcription is the process whereby genetic instructions or materials in DNA are transmitted to messenger RNA in the nucleus.
It involves initiation, enlongation and termination.
Translation is a process that occur in the RIBOSOMES or endoplasmic recticulum after transcription of RNA and it is the process where genetic code in the messenger RNA is decided or translated to a sequence of amino acid.

How would the coils in the middle of the diagram change
to show a longitudinal wave with higher energy?
They would be farther apart.
They would be closer together.
O They would be shaped like a hill.
O They would be shaped like a valley.
Answer:
They would be shaped like a hill.
Explanation:
A longitudinal wave with higher energy have greater amplitude. Amplitude is the distance between the crust and trough of the wave. Crust is the upper part of the wave while trough is the lower part of the wave. If the distance between crust and trough of the wave is higher so the amplitude is also greater and we can say that the wave contains high amount of energy and vice versa. The shape of the wave just like a hill.

When glycogen phosphorylase is phosphorylated Group of answer choices its activity decreases. its activity increases. its activity is unaffected. none of these because that enzyme doesn't get phosphorylated.
Answer:
The correct answer is that its activity increases.
Explanation:
Glycogen phosphorylase comes under the category of phosphorylase enzymes. The mentioned enzyme catalyzes the rate-limiting step in the process of glycogenolysis within the animals. The sequential phosphorolysis of glycogen to discharge glucose-1-phosphate is catalyzed by the enzyme glycogen phosphorylase. Therefore, glycogen phosphorylase plays an essential part in the use of liver and muscle reserves of glycogen. After undergoing phosphorylation, the activity of the enzyme increases.
