Kangaroos are mammals that lack a placenta. Therefore, they must have an alternate way of supplying the developing embryo with

Answers

Answer: yolk sac

explanation:

the placenta does not develop for a long time so the alternate way of supplying the developing embryo is through the yolk sac which the embryo can receive nutrients and respiratory gas exchange through which the placenta will be formed later.

Kangaroos are mammals that lack a placenta; therefore, they must have an alternate way of supplying the developing embryo with nutrients, as these should be passed from the mother to the embryo during the time of pregnancy.

What is the function of the placenta in pregnancy?

The placenta is an organ that develops during pregnancy to provide nourishment to the growing fetus and to remove waste products from the baby's blood and is attached to the wall of the uterus and connected to the baby by the umbilical cord, it is responsible for producing hormones that maintain the pregnancy, such as progesterone, which helps to keep the lining of the uterus thick, also produces human placental lactogen, which helps stimulate the mother's mammary glands to produce milk.

Hence, kangaroos are mammals that lack a placenta; therefore, they must have an alternate way of supplying the developing embryo with nutrients, as these should be passed from the mother to the embryo during the time of pregnancy.

binary fission asexual reproduction in which a single cell divides into two with no exchange of genetic material; reproduction method of bacteria

budding A kind of asexual reproduction involving the growth of a new individual from part of an older organism. It can also refer to uneven distribution of cells that results in one cell receiving most of cell contents. In grafting, budding involves reducing the scion to a singular bud.

central disk =  The central portion of a starfish. The arms of a starfish radiate from the central disk.

colony = A group of organisms attached to one another after undergoing asexual  reproduction from a common parent.

conidia = A special kind of asexual spore found in many kinds of fungi.

multiple fission = A kind of asexual reproduction in which a single cell undergoes many mitotic divisions in the nucleus and a number of daughter cells are produced all at once.

propagation = The act of propagating or establishing and growing new plants.

protist = A one- or few-celled organism with chromosomes. Many have characteristics of both animals and plants.

regeneration = A phenomenon in which organisms break into two or more parts and then each part grows into a new individual.

spore = A small, resistant cell that can grow into a new organism. They may be produced either by meiosis or mitosis.

unicellular = One-celled.

The scientist noticed that oval is dominant over triangular with regard to snout shape. Additionally, long is dominant over short with regard to tail length. To determine if these traits are linked, two individuals that are heterozygous for both traits were crossed. The data in the table represent the number of offspring produced by this dybrid cross. Phenotypic ratio represents the predicted proportion of offspring with each set of traits that would be produced if the traits independently assort. What can be determined about these traits based on Chi-square analysis? A) These traits do not assort independently. B) There are not enough data to calculate a Chi-square value. C) A Chi-square analysis cannot determine linkage. D) These traits assort independently.

She is working there for a week when one evening a man in the recovery room is being closely monitored after surgery. The signs are not good. He recovers consciousness. The doctors inform him of the situation. They leave the recovery room. The man calls the nurse over and asks for a pen and some paper. Thinking that he might die, and do so soon ,he informs her that he needs to write a brief letter to someone. She finds pen and paper and gives it to him. He writes his note and writes the address and asks the nurse to send it out for him. She agrees. As she is taking the pen and papers back from him the recovery room supervisor enters and observes her. The supervisor calls her over and inquires as to what she was doing. When the newly hired nurse reported that she had assisted the man in writing a letter and took it to mail it for him , the supervisor responded that : "It is not your responsibility to do such things." The new nurse responded that she was simply trying to help the man and had agreed to mail the letter. The supervisor replied with: "This is not a post office!" The new nurse repeated that she was only attempting to help the man. That he might die shortly. The supervisor wrote up the new nurse for subordination. The new nurse was dismissed from the hospital as she was in her probationary period. What was the new nurse to do and why?
