When you cross two heterozygotes with the genotype Aa, the offspring will be: <span>Parents: Aa x Aa</span>
<span>F1 generation: AA Aa Aa aa</span>
<span>This means that ½ of the offspring will be heterozygous, ¼ will be homozygous (dominant) and ¼ will be homozygous (recessive).</span>
Answer:
The streaks made by the limonite are yellow, and the streaks made by Mary and Jim’s sample are brown. Therefore, they are not the same mineral. The rock is not made of limonite.
Explanation:
PLATO
Answer:
The correct answer is - option 1. 930 kilocalories.
Explanation:
In every ecosystem, the energy is passed from one form to another and there is a lot of loss of the energy as heat in the cellular process. There is a transfer of only 10% of each level of the trophic level.
Algae is the producers in this aquatic ecosystem so the primary consumer will get 10% of the energy that is present in plant tissue (93000kcal) which will be 9300 Kcal and second producers will get 10% of this will be 930Kcal.
Thus, the correct answer is option 1. 930 kilocalories.
Answer:
C
Explanation: A fish can live in water and get carbon in the air bubbles but it's not enough carbon to thrive off of so the fish may need to eat other fish or plankton in the water. The second example A wolf would get its carbon from both the air and water but would still need extra carbons so that is why it would hunt a deer to consume its carbons. Also, the deer would get its carbons from the air, water, and grass. the grass would get its carbons from water and air. NOW DO YOU GET IT EVERYTHING IS CARBONS AND LIVES OFF OF THEM AND IT WILL ALWAYS BE THAT WAY!
Answer;
-Birth defects
Explanation;
In animals, long-term exposure to DDT can cause death or severe birth defects.
-DDT stands for dichloro-diphenyl-trichloro-ethane. It is an insecticide/pesticide previously used on crops. DDT has an adverse impact on many organisms such as crayfish, fish, shrimp, and other animals such as mammals.
DDT is slightly to moderately acutely toxic to mammals, including people, if eaten.Animals given potentially fatal doses of DDT develop liver lesions and those given DDT over a long period of time develop liver changes. In these animal populations DDT may cause birth and reproductive defects.
