Answer:
D
Explanation:
This involves a dihybrid inheritance I.e. two genes are being passed on. During meiosis, specifically, the Prophase stage, homologous chromosomes (similar but non-identical chromosomes received from each parent) line side by side. According to the question, one chromosome contains A and B alleles and its homologue, received by the other parent carries a and b alleles. This means that the diploid individual has a genotype AaBb for that gene.
According to Mendel's law of independent assortment, the alleles separate independently of one another into gametes. I.e. allele A and a separates into the gametes without affecting alleles B and b of the other gene.
Crossing-over, which is the exchange of chromosomal segment occurs between the two homologues. Hence, the exchange of chromosomal segments containing alleles in the individual will possibly produce four gametes with the genotypes: AB, Ab, aB, ab.
Items such as sheet metal, treated lumber, corn syrup, and plastics are examples of processed materials.
Processed materials are materials which have been refined or built by humans from raw materials.<span> Processed materials are different from component parts as they become part of a finished product and don't retain their original identity.
</span><span>Ceramic is a processed material. You have to add several materials, heat them, sinter them and then you get ceramic.</span>
Answer:
Saturated fats have no double bonds in their chemical structure. They are “saturated” with hydrogen atoms. Because of their chemical structure, they have a solid consistency at room temperature. Unsaturated fats are typically liquid at room temperature. They differ from saturated fats in that their chemical structure contains one or more double bonds. They can be further categorized as: 3
Monounsaturated fats: This type of unsaturated fat contains only one double bond in its structure. Monounsaturated fats are typically liquid at room temperature and include canola oil and olive oil.
Polyunsaturated fats: This type of unsaturated fat contains two or more double bonds in their structure. They are liquid at room temperature. Polyunsaturated fats include safflower oil, sunflower oil, and corn oil.
Explanation:
Answer:
Compare the carboniferous period to the Devonian period is compared below in details.
Explanation:
In the Devonian Period, woods and land plants developed and vertebrates performed their presentation. Four-legged vertebrates developed during the Carboniferous Period, which created an improvement in the number of land-based bodies. The climate of the continental inland sections was very heated through the Devonian Period and usually quite dry while woods and land plants developed during the Carboniferous period.
Climate change is already beginning to transform life on Earth. Without action, the impacts of climate change threaten to catastrophically damage our world. But by rallying people around the world to be a part of the solution, together we have the power to limit the effects of climate change.
i hope this helps!!
