Answer:
Option D
Explanation:
In 1972, the fluid mosaic model was proposed by S. J. Singer and G. L. Nicolson to describe the structure of the plasma membrane found I living cells. The model describes the plasma membrane to possess components including phospholipid, proteins and cholesterol.
The phospholipid is arranged in two layers comprising of glycerol, two fatty acids and a phosphate group. The fatty acids which forms the tail are hydrophobic (water-fearing) while the phosphate group is water-loving (hydrophobic) giving the plasma membrane an AMPHIPATHIC nature. The other component as proposed by the model are membrane proteins and cholesterol, all responsible for the fluidity of the membrane.
<span>After ovulation, an oocyte, or egg cell, remains viable in the female body for up to 24 hours. The generally accepted lifespan in a woman's body is 12 to 24 hours for the egg and up to five days for the sperm cells. Intercourse occurring as many as five days prior to ovulation, therefore, could potentially result in pregnancy.</span>
Answer:
C) they lack lignified vascular tissue. (
Since they do not have vascular tissues, they are not able to develop vertically like the trees we know.)
Explanation:
A)
Plants do not have "sperm". They have sporophytes or gametophytes.
B) No specific parasitic bacteria of bryophytes are known.
D) In fact, they have. Although they require water for their reproduction, some species of bryophytes are found in deserts.
E) Rhizoids are not weak, otherwise they would not have the ability to keep bryophytes attached (mosses).
Answer:
In my opinion, a reduction in our use of energy would not be a historical step backwards.
Explanation:
We already know that humanity's consumption of fossil fuels is wreaking havoc on the ecosystem. Fossil fuels pollute the environment where they are generated and utilized, and their continued usage harms the climate of the entire world. Nonetheless, altering our behaviors in a significant sense has proven to be quite difficult. As a result, it is not impossible to reduce our energy use significantly, but we may take little efforts to change the way we create energy, such as using fossil fuels. Because fossil fuels are so detrimental to our environment, we should try to reduce its use, but not at the risk of improving our surroundings. There are several methods to change the way we utilize energy now into something more sustainable.
