Which statements are true of all plants? Check all that apply. All plants are vascular. All plants are multicellular. All plants

GarryVolchara [31]

<u>Correct option/s </u>:

All plants are multicellular.

All plants are eukaryotic.

All plants are autotrophic.

<u>Explanation</u>:

Not all plants are vascular, for example mosses. They don't have specialized system for transport of water and solutes. Therefore, Option 1 is false.

Only bacteria, protista and yeast are unicellular. Rest all the organisms are multicellular. Thus option 2 is true.

Only bacteria are prokaryotic, rest all organisms are eukaryotic, including all the plants. Option 3 is true.

Plants are the only organisms which are autotrophic. Although apart from this mode of nutrition, plants can be parasitic or carnivorous as well. But primarily they all are autotrophic. Option 4 is true

Not all plants need sunlight, some get energy from the chemical substances from their surroundings. Option 5 is False.

Plants reproduce by sexual as well as asexual means. Not all plants reproduce sexually. Option 6 is false.

The structure labeled ________ can be influenced by hormones to change the concentration of the urine.

puteri [66]

Answer: The diagram attached is known as the nephron,it is labelled from A to E, the structure labelled E which is known as the COLLECTING DUCT can be influenced by hormones to change the concentration of urine.

Explanation: Antidiuretic hormone ADH is one of the hormones that is produced by the anterior lobe of the pituitary gland of the endocrine system,this antidiuretic hormone performs certain functions of which one is that it helps to increase the rate and amount of water that is reabasorbed in the distal convulated tubule of the nephron during the second stage of urine formation,when these water are reabsorbed,the urine being produced becomes more concentrated and there is a further reduction in the volume/quantity of urine produced.

When this volume of urine is decreased/reduced, plasma osmolarity increases in reaction to the decreased volume of urine.

Urine are also reabsorbed in the collecting duct.

If a boy exhibits a sex-linked trait that is carried on the X chromosome, what must be true?

ad-work [718]

Answer;

C. His mother carried at least one allele for that trait

Explanation;

-Men have a single allele of each gene on the X chromosome, inherited from their mother, and a single allele of each gene on the Y chromosome, from their father.

-A sex-linked trait is a trait that is controlled by a gene or an allele located on the sex chromosome.

-X-linked traits are maternally inherited from carrier mothers or from an affected father. Each son born to a carrier mother has a 50% probability of inheriting the X-chromosome carrying the mutant allele.

iren2701 [21]

Answer:

An environmental factors that can harm a developing embryo and fetus.

Explanation:

Teratogens are kind of agents that create disturbance to the developing fetus or embryo or may create birth defects in a child.

Teratogens may be a drug, or chemicals or radiation and material infection.

It halt pregnancy or form congenital malformation.

They are environmental factors which results in permanent structural and functional malformation that in turn leads to death of the embryo.

Some example of potential teratogens are-

Caotopril,lisinoprils,ramipri,alcohols,antibiotics such as tetracycline,doxycycline,streptomycin,wrfarin,seizure medicines,phenytoin,valptoic acid,carbamazepine,anti cancer or anti metabolite drugs like methotrexate,penicilline,depen ,anti thyroidal drugs such as thiouracil,carbimazole etc.
