Homologous chromosomes may exchange segments; this is called crossing over. crossing over increases genetic variability. when does crossing over occur?
Answers
A trade of chromosome segments among non-sister homologous chromatids happens and is referred to as crossing over.
Crossover happens while chromosomes, usually homologous times of the equal chromosome, spoil after which reconnect however to the specific quit piece. If they spoil on the equal location or locus withinside the collection of base pairs, the end result is an trade of genes, referred to as genetic recombination.
What are homologous chromosome?Homologous chromosomes are made from chromosome pairs of about the equal length, centromere position, and marking pattern, for genes with the equal corresponding loci.

Even-aged management practices involves clearing trees that
are all the same height
b. are all the same weight
C. are all near the same age
d. are all of widely different ages
Please select the best answer from the choices provided
Answers
Answer: C. Are all near same age.
Explanation: Even-aged firewood management practices refer to the practice of clearing of trees that "are all near the same age"as this technique is usually adopted to maintain the proportion and continuity of various species of trees(thus, cutting of the trees of same age). This practice is employed to minimize the costs and attain a coeval and comrade group of trees. It proves quite beneficial in reestablishing the succession of a native breed. It involves the selection of trees at first depending on the size, desirable species, etc. followed by clearcutting of unmerchantable(undesired) trees. This technique is usually adopted to maintain the proportion and continuity of various species of trees.
KEYWORD- “Even- aged”which means clearing all trees that are even to all near the same age of tree.

Explanation:
Have a great rest of your day
#TheWizzer
The color that is reflected back to cause plants to appear green is the color green, as that is reflected back, the eyes can capture it, and as a result, the plants appear to be green.
What is the reason behind plants being green?Plants are green because of the presence of chlorophyll, a pigment found in plant cells. and this green color from sunlight is reflected back to the environment, and chlorophyll is crucial for photosynthesis, the process by which plants convert sunlight into energy, Photosynthesis occurs in specialized organelles within plant cells called chloroplasts. This absorbs light energy from the sun, and the absorbed energy is then used to power a series of chemical reactions that convert carbon dioxide and water into glucose, a form of sugar that the plant can use for energy.
Hence, the color that is reflected back to cause plants to appear green is the color green.

Suppose a new resort hotel is built on a hawksbill sea turtle nesting site, and hotel guests start removing the queen angelfish from the nearby reef to stock their home aquaria. If the hawksbill sea turtles and queen angelfish are removed, which organism is most likely to benefit?.
Answers
Answer:
Sponges, Anemones, Squid and Shrimp.
Explanation:
Those are the organisms that the sea turtle feed on.
Sponges, Anemones, Squid and Shrimp are most likely to benefit since the sea turtles and angelfish feed on them.
What happens if hawksbill sea turtles and queen angelfish are removed?Hawksbills contribute to the preservation of coral reef health. Reef fish have easier access to food because they clear sponges and other prey off the reef's surface. They are also valuable for tourism and have cultural significance.
Queen angelfish are omnivores that primarily eat algae and sponges. They are opportunistic and will consume jellyfish, soft corals, and sea fans. Young fish clean larger kinds of fish by removing parasites from their skin so that they can be eaten.
The populations of the organisms that Hawksbill Sea Turtles and queen angelfish consume, such as sponges and sea urchins, would probably explode if they became extinct. This would result in widespread erosion and possibly the collapse of marine ecosystems like coral reefs.
