Answer:
Lichen
Explanation:
Most lichen are sealing off stone surfaces and can prevent erosion. Lichen can also exudate chemical weathering agents, which facilitate mineral neoformation, e.g., turning rock surfaces into soil.
Are both strands of DNA copied continuously during replication? Explain your answer.
Answer:
Since the two strands of a DNA double helix are antiparallel, this 5′-to-3′ DNA synthesis can take place continuously on only one of the strands at a replication fork (the leading strand). On the lagging strand, short DNA fragments must be made by a “backstitching” process.

Answer: Encourage students to set up a germination experiment by placing the seeds in different conditions, such as light vs. dark, or wet vs. dry. Moreover, they need to pot the same seed in more than one pot.
Explanation:
This option provides a clear and practical approach to the seed germination investigation. By setting up different conditions for the seeds, such as light vs. dark or wet vs. dry, the students can observe and compare how these conditions affect the germination process. Additionally, potting the same seed in multiple pots allows for a controlled comparison within the experiment.
By manipulating these variables, the students can gather valuable data and observations regarding the influence of light and moisture on seed germination. This approach promotes a hands-on and investigative learning experience, encouraging students to actively engage with the scientific process while documenting the changes that occur over time, such as the emergence of roots and shoots.

Think and Discuss: In what ways are plants and animals dependent on each other? ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Answer:
Energy exchange, Nutrient cycling, Pollination, Habitat
Explanation:
Plants and animals are dependent on each other in many ways. Some of the most important ways in which they are interdependent include:
1. Energy exchange: Plants and animals are linked through the transfer of energy. Plants use the energy from sunlight to produce glucose and oxygen through photosynthesis, while animals consume plants and plant products as a source of energy.
2. Nutrient cycling: Plants and animals play a crucial role in the cycling of nutrients in the environment. Plants absorb nutrients from the soil and convert them into organic matter, which is then consumed by animals. When animals excrete or decompose, the nutrients are returned to the soil and can be used by plants again.
3. Pollination: Many plants rely on animals, such as bees and butterflies, to pollinate their flowers and fertilize their seeds. In turn, animals rely on plants for food and shelter.
4. Habitat: Plants and animals are often found together in ecosystems, where they interact with each other and their physical environment. For example, plants provide habitat and shelter for animals, and animals disperse the seeds of plants and help them to reproduce.
Overall, plants and animals are closely interconnected and rely on each other for their survival and well-being.

4. Name three agents of dispersal. In each case, give an example of a plant whose seeds are dispersed by the agents
Answer:
Three agents of dispersal are:
Wind: Some plants have adaptations that allow their seeds to be carried by the wind. Examples include dandelions, which have feathery bristles attached to their seeds that help them float through the air, and maple trees, which have winged seeds called samaras that spin as they fall, allowing them to travel long distances.Animals: Some plants have adaptations that allow their seeds to be dispersed by animals. For example, burrs have hooks or spines that attach to the fur of animals, allowing the seeds to be carried away from the parent plant. An example of a plant that uses this method is burdock. Some fruits, such as berries, are also eaten by animals, which then excrete the seeds in their droppings, allowing them to be dispersed over a wider area. An example of a plant that uses this method is the blackberry.Water: Some plants have adaptations that allow their seeds to be dispersed by water. Examples include coconuts, which have a fibrous husk that can float on water, allowing the seed inside to be carried away by ocean currents, and water lilies, which have seeds that float on the surface of the water and are dispersed by the movement of the water.PLEASE GIVE ME BRAINLIEST!

Explain why it makes sense that the levels of estrogen and progesterone are low in blood of a female during menstruation
PLS HELP ! URGENTTT
I'LL GIVE BRAINLY
Answer:
At the beginning of the follicular phase, the lining of the uterus (endometrium) is thick with fluids and nutrients designed to nourish an embryo. If no egg has been fertilized, estrogen and progesterone levels are low. As a result, the top layers of the endometrium are shed, and menstrual bleeding occurs.
Explanation:
Three Anacharis plants were placed inside inverted test tubes filled with water. One test tube was exposed to low light, another to medium light while another was exposed to high light. The table provided shows the results of this experiment. Notice that more oxygen was produced by the Anacharis in high light.
Based on the information provided, what is the difference in volume (in mL) of oxygen produced between the low light and high light plants after 45 minutes? Record your answer below
Answer value
Answer:
Anacharis in High Light produces more mLof oxygen per min than Anacharis in Low Light Anacharis and in Medium Light.
Explanation:
The increased light intensity also increases the rate of photosynthetic activity. As photosynthesis occurs, the energy from sunlight, along with CO2 is converted to chemical energy in the form of glucose.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
or Carbon dioxide + water = energy (glucose) + oxygen
Photosynthesizing cells in green plants produce oxygen as a waste product. As this process is rate-limited, certain factors may increase the reaction rate. These include:
carbon dioxide concentration
water availability
ambient temperature
light intensity;

predict percentage of offspring with a trait
predict genotypic probabilities
track inherited traits through generations
identify the genotype of parents
A pedigree chart is used to track inherited traits through generations.
A pedigree chart is a visual tool that represents the inheritance patterns of specific traits or genetic conditions within a family. It helps to trace the occurrence of traits, diseases, or genetic conditions across multiple generations by depicting the relationships between individuals and their affected or unaffected status.
Pedigree charts are commonly used in genetics and genetic counseling to analyze patterns of inheritance, identify carriers of genetic disorders, determine the probability of passing on certain traits or diseases, and study the transmission of traits within families. By examining the patterns of inheritance in a pedigree chart, one can gain insights into the mode of inheritance, such as autosomal dominant, autosomal recessive, or X-linked inheritance, and make predictions about the likelihood of certain traits or conditions appearing in future generations.
