Answer:
Epigenetic marks (e.g., DNA methylation patterns) in older twins are more pronounced than in younger twins
Explanation:
Epigenetics refers to any heritable phenotypic change that does not involve alterations in the DNA sequence but impacts gene expression. Epigenetic modifications can be classified into three types: DNA methylation, histone modifications (i.e., acetylation, methylation, phosphorylation, etc) and regulatory non-coding RNA (ncRNAs) pathways. Epigenetic modifications in (epi)genome enable to explain how two individuals with identical genetic material (such as monozygotic twins) can have different phenotypes. In older twins, epigenetic differentiation will be higher than in younger ones due to the divergence between epigenomes as a result of age.

Producers, consumers, and decomposers work together to conserve the carbon on Earth. Which statement is the correct model of the carbon cycle? O Producers use carbon to make food, consumers take in carbon from the organisms they eat, and decomposers break down remains and release carbon. O Producers take the carbon from carbon dioxide in the air, while consumers and decomposers use carbon to produce carbon-containing molecules like sugars. O Producers produce carbon from the sun, consumers consume carbon from the organisms they eat, and decomposers break down remains and release carbon. O Producers make organisms that produce carbon, consumers eat and release the carbon from their food, and decomposers make carbon from the producers.
Answer:Producers use carbon to make food, consumers take in carbon from the organisms they eat, and decomposers break down remains and release carbon.

Explain why plants cells require both chloroplasts and mitochondria to meet their energy needs
Answer:
chloroplast is where photosynthesis takes place, and mitochondria stores and releases the energy, it's like having a battery but no cord to charge anything
Explanation:
Which of the following is NOT true of Chlorophyll?
A) It reflects all the colors of light but absorbs the green.
B) It reflects the green wavelengths of light and absorbs all the rest.
C) It is essential for photosynthesis?
Answer: A.It reflects all the colors of light but absorbs the green.
Explanation:
Photosynthesis, which gives plants their green hue, requires chlorophyll. Therefore, option (A) is not true.
What is chlorophyll?Chlorophyll, the pigment that gives plants their distinctive green hue, is crucial to the process of photosynthesis, which provides energy for a plant's metabolism, growth, and reproduction. Because chlorophyll does not absorb the green wavelengths of white light, it is chlorophyll that gives plants their green hue. The plant appears green because it reflects that particular light wavelength. Autotrophs are plants that produce their own sustenance through photosynthesis.
The stroma, which is the area between the thylakoid and chloroplast membranes, is where the chlorophyll, the green pigment, is found.

What affect does the toxic algae bloom have on local communities and ecosystems?
Answer:
Algal blooms can reduce the ability of fish and other aquatic life to find food and can cause entire populations to leave an area or even die. Harmful algal blooms cause thick, green muck that impacts clear water, recreation, businesses and property values.

Explain how water circulates between the hydrosphere and atmosphere to create weather and climate. Use complete sentences and give at least three supporting details.
Answer:
Due to evaporation, weather and climate are created.
Explanation:
Water circulates between the hydrosphere and atmosphere with the help of evaporation. Evaporation occurs on the water bodies where the water molecules evaporate and goes to the atmosphere forming clouds. These clouds are responsible for rainfall and snowfall in different regions and as a result weather and climate are created. This cycle of water in the atmosphere is known as meteorological cycle.

In this lab, you used a variety of media with a NaCl concentrations ranging from 0.5% to 15%. On which of these media are the bacteria most likely to undergo osmotic lysis
Answer:
none of these media
Explanation:
Bacteria have resilient cell walls composed of cross-linked peptidoglycan that acts as a cross-linked wire and thus prevents them from osmotic lysis. In consequence, bacteria are generally able to grow in hypo-osmotic conditions. Moreover, all the media indicated above are hypotonic compared to the bacterial cells, i.e., they have a lower solute concentration compared to the bacterial cytoplasm. In hypotonic media, bacteria can take up water from the external solution by osmosis.

is the energy an object has because of the movement of its molecules.
A. Heat
B. Thermometer
C. Particles
D. Temperature
Temperature is a measure of kinetic energy because molecular motion is regarded as kinetic energy. The average kinetic energy of the molecules in a gas increases as its temperature rises, resulting in more motion. Thus option D is correct.
What is kinetic energy?A particle or an item that is in motion has a sort of energy called kinetic energy. An item accumulates kinetic energy when work, which involves the transfer of energy, is done on it by exerting a net force.
The molecular kinetic energy rises and the molecules start to move faster when heat energy is added to a system.
By increasing the temperature, the velocity of the particles is accelerated.
In contrast, lowering the temperature slows down the motion of the particles until it eventually stops entirely at absolute zero (0 K). The particles will have kinetic energy since they are moving.
Therefore, Temperature is the energy an object has because of the movement of its molecules.

Raquel is having difficulty becoming pregnant, and her doctor believes it could be due to the position of her uterus. Which organ should the body of the uterus be immediately superior to in the pelvis
The given question is incomplete, the complete question is:
Raquel is having difficulty becoming pregnant, and her doctor believes it could be due to the position of her uterus. Which organ should the body of the uterus be immediately superior to in the pelvis? Multiple Choice Urinary bladder Rectum Ovary Vagina
Answer:
The correct answer is urinary bladder.
Explanation:
In the pelvis, the urinary bladder is the organ to which the body of the uterus would be immediately superior. In the pelvis or the lower abdomen, a pear-shaped hollow composition, present between the urinary bladder and the rectum is known as the uterus. The structure or the composition located superiorly lateral to the uterus body and associated with the utero-ovarian ligament is known as the ovary. The vagina and the rectum are located underneath the uterus or the uterine cavity.
