Answer:fertilization
Explanation:
The process of genetic recombination which involves genes from both parents is crossing over. This process occurs during prophase I of meiosis, when homologous chromosomes pair up and exchange genetic material.
Explain the process?A portion of each parent's chromosome is swapped during this process, resulting in two new chromosomal combinations that are distinct from those of either parent. Genetic variety among the progeny is produced as a result of this process, which is advantageous for evolution.
The process of crossing over is random, therefore it is unpredictable which chromosomal segments will be exchanged. This is crucial for fostering genetic diversity because it allows for a wider variety of genetic combinations to be produced when genetic material is exchanged.
As portions of each chromosome will be exchanged during crossing over, this procedure also aids in ensuring that the offspring obtain a combination of genetic material from both parents.

Mary pushes her cart across the floor with a force of 150N for a distance of 10m. What is the work done on the cart?
Answer:
1500Joules
Explanation:
Work done, denoted by W, can be calculated using the formula:
Work done (W) = force (F) × distance covered (d)
According to the information in this question, Mary pushes her cart across the floor with a force (F) of 150N for a distance (d) of 10m.
Hence, work done (W) by the cart is:
W = 150N × 10m
W = 1500 Newton.metre (N.m) or Joules (J).

We need to cross a heterozygous axial, hybrid round seed plant with a hybrid axial, heterozygous round seed plant. When referring to a hybrid plant for a trait, we are meaning that the plant is heterozygous for that trait.
Let us assume that round is the dominant trait, codified by a diallelic gene, so
R is the dominant alleler is the recessive alleleLet us also assume that axial is the dominant trait, so
A is the dominant allelea is the recessive alleleCross:

Shawn explains that many studies have shown that directly spraying bees with fungicides doesn't harm them. Are those results consistent with what Shawn has discovered? Explain your answer in a few sentences.
Answer:
Yes.
Explanation:
Yes, the results will be consistent of spraying bees with fungicides because the fungicides affect the growth of fungus not the bees. fungicides are the chemicals kills fungal growth while on the other hand, insecticides will kill the insects such as ants, bees etc. If the Shawn apply insecticide on the bees, it will kill the bees due to its effectiveness so that's why the results of the directly spraying bees with fungicides will always be consistent due to its ineffectiveness.

Describe one method to reduce the air pollutants released from a coal burning power plant
Answer:
A method to reduce the air pollutants released from a coal burning power plant is carbon capture.
Explanation:
Carbon Capture: It separates CO2 from emissions sources and recovers it in a concentrated stream. The CO2 can then be injected into the soil underground for permanent storage, or sequestration. Reuse and recycling can also reduce the environmental effects of coal production and use.

Part A: Design a food chain with four trophic levels, and identify the organism in each level. What happens to energy as it travels from the bottom up? (3 points)
Part B: Can humans ever occupy the lowest, or first, trophic level? Why or why not? (1 point)
Answer:
Part A: Primary producer - plants (ex: sunflowers), Primary consumers- herbivores(ex: rabbits), Secondary consumers - omnivores and carnivores (ex: snake), tertiary consumers - omnivores and carnivores (ex: foxes), A-p-e-x predators - can be omnivores or carnivores (ex: coyote)
Energy decreases as it travels from the bottom of an energy pyramid, every time energy passes from one tropic to another, the predator only gets 10% of the total energy, or the stored energy, the rest of the energy has already been used up.
Part B: Humans cannot ever occupy the lowest or first tropic level, because the first tropic level is for producers like plants, humans are not producers and therefore cannot be at the first tropic level.
what did humans evolve from I am creating a a evolution chain I know this can be considered a unintelligent question I am just not positive on what we evolved from
Answer: Human evolution, the process by which human beings developed on Earth from now-extinct primates. Viewed biologically, we humans are Hono Sapines, a culture-bearing upright-walking species that lives on the ground and very likely first evolved in Africa about 315,000 years ago.
Human evolution is not linear manner it is a web, in the process of evolution primates lead to the emergence of homo-sapiens, which is distinct from the hominid family.
How did humans evolve?Human evolution is observed in a web manner not linear in evolutionary history primates lead to the homo-sapiens which is distinct from another family of hominids.
The hominid family includes great apes that diverged from the gibbons 15-20 million years ago. Evolution involves some studies, genetic studies, and h behavioral studies.
Anatomically it is observed in Africa 300000 years ago humans appeared, these studies were observed anatomically as the origin of humans.
Therefore human evolution is observed in a web manner not linear.

C,cells, organelles, proteins, organisms
D,organelles, cells, proteins, organisms

Cells, organelles, proteins, organisms describes the organization within multicellular organisms from least complex to most complex. The correct option is C.
What are multicellular organisms?Multicellular organisms include a mixture of more than one cell, with differentiating groups of cells performing specialized functions.
Early stages of development, cells in humans distinguish towards becoming nerve cells, skin cells, muscle cells, blood cells, as well as other types of cells.
All animals, land plants, and most fungi are multicellular, as are numerous algae, with the exception of slime molds and social amoebae such as the genus Dictyostelium, which are partially unicellular and partially multicellular.
Cells, organelles, proteins, and organisms describe the organization of multicellular organisms in descending order of complexity.
Thus, the correct option is C.

In a sample of double stranded dna if 19% of the nitrogenous bases are guanine what percent of the nitrogenous bases are adenine
Answer:
31%
Explanation:
Chargaff's law says the amount of A (adenine) = T (thymine) and G (guanine) = C (cytosine). If
G = 19% then C= 19%
19% + 19% = 38%
100% - 38% = 62%
62% for A and T
Divide by 2 and you get
31%
Can someone name and explain each lymph organ?
Answer:
The lymphatic system consists of all lymphatic vessels and lymphoid organs. For example, the lymph nodes, spleen, thymus as well as the lymphatic tissue found in the small intestine (Peyer’s patches) and throat (adenoid tonsils, palatine and tubal tonsils), to name a few, all represent lymphatic organs.Hence, rather than representing a single organ, the lymphatic system comprises a circulatory network of vessels and lymphoid tissue and cells in every part of the body. It works together closely with the blood-producing (haematopoietic) system in the bone marrow, thereby playing a vital role in immune responses to protect the body from various pathogens. Also, the lymphatic vessel network helps transporting nutrients and waste products in the body.

Answer:
If it is the scene that I think you're referring to, they were sitting in a group on rocking chairs, cutting yarn.
Explanation:
in Greek mythology, these women are the three Fates, named Clotho, Lachesis, and Atropos. In mythology, a thread represented someone's lifeline, and when the Fates cut your thread, it meant your life was over and you died.
In this specific scene, from The Lightning Thief, the Fates are seen cutting a blue piece of yarn, which makes Percy's friend Grover nervous because he believes they've just cut Percy's lifeline.
