Which remains the same during a chemical reaction?

Answers

Answer 1

Answer:

In a chemical reaction the total mass of all the substances taking part in the reaction remains the same. Also, the number of atoms in a reaction remains the same. Mass cannot be created or destroyed in a chemical reaction

Answer 2

Because matter is not created or destroyed in a chemical reaction, the total mass of reactants is the same as the total mass of products.

C) Fetal waste is removed through the ductus venosus; infant waste is removed through the rectum.


D) Fetal waste is removed through the large intestine; infant waste is removed through the ductus venosus.

Answers

Answer: A) Fetal waste is removed through the chorion; infant waste is removed through the rectum.

Explanation:

A developing fetus is surrounded by chorion which is an outer membrane. The role of the chorion is to protect the embryo and provide nutrition to it in the form of blood supply. It helps in getting rid of waste products from the developing fetus that goes into the mother blood to remove out of her body. In case of infants the rectum is the last part of the digestive tract and it receives the waste in the form of fecal matter from small intestine which is removed out through the rectum.

Explanation:

Many snakes and lizards live in the desert, where temperatures are high during the day and cold at night. How does the temperature range affect the size of the snakes and lizards?


A. High daytime temperatures allow them to grow as large as the food supply will allow.


B. Cold nighttime temperatures limit their size, because large ectotherms need a long time to warm up in the sun.


C. High daytime temperatures limit their size, because large endotherms would overheat on very hot days.


D. Cold nighttime temperatures limit their size, because large endotherms would lose too much of their body heat.

Answers

Answer:

A. High daytime temperatures allow them to grow as large as the food supply will allow.

Explanation:

Snakes and lizards are cold-blooded animals. This type of animal cannot maintain a constant body temperature and depends on the temperature of the environment to keep warm and keep its organs and metabolism working.

Room temperature is so important to these animals that they even determine the size of their bodies. For these animals, high temperatures allow them to have their metabolism accelerated, so they can grow as much as the availability of food allows. On the other hand, if there is not enough food, or very cold temperatures, they will need to be smaller in size, as the metabolism will be slow.

Case Study The Selkirk Rex cat is a breed known for its curly hair. The allele responsible for this curly hair exhibits incomplete dominance. Two copies of the allele yields very curly hair, a slender body, and large ears. One copy of the allele yields a more sturdy body, wavy hair, and smaller ears. Cats with one copy are preferred for professional cat shows. A man from Argentina recently inherited two sister Selkirk Rex cats from a relative and is interested in breeding them to produce more curly-haired cats. One cat carries two copies of the Selkirk allele. The other Selkirk Rex cat carries one Selkirk allele. What genotypes should he seek in mating partners for his cats to produce the most heterozygous kittens possible in the next generation? Note: he doesn't want any kittens that do not have wavy or curly hair. What genotypes should the breeder choose for mates for his Selkirk cats? Choose the beſt answer from the choices below to maximize the number of heterozygous kittens AND maintain the mutation in the population for future breeding. For the SS cat, he should choose Ss. For the Ss cat, he should choose 55. For the SS cat, he should choose ss. For the Ss cat, he should choose Ss. For the SS cat, he should choose 55. For the Ss cat, he should choose Ss.

A. The birth rate was equal to the death rate.

B. The death rate was greater than the birth rate.

C.The rate of emigration was equal to the birth rate.

D. The rate of immigration was greater than the death rate.

Answers

Answer:

A. The birth rate was equal to the death rate.

Explanation:

The point X is the carrying capacity and this pajae could be ascribed as the plateau stage of population growth, whereby the maximum number of individuals of a particular species which the environment can support has been reached. Hence, giving a long, flat area of the logistic growth curve. At the stage marked x, growth would seize as the population hovers to attain equilibrium with the natality and fatality rate becoming equal, that is birth rate will be equal to the death rate in the population.
