Answer:

2) possess tubular or stalk-like extensions of their cells.

Explanation:

Appendages are tubular or stalk like extensions found on bacterial surface and utilized for specific function by bacteria. Some appendages are strongly anchored on surface while other are loosely attached.

Three important appendages in bacteria are;

Flagella; locomotion

Fimbriae; stick bacteria on the surface of host

First question: When the population of lynx increases, the population of hares will decrease due to being over-hunted by more predators than usual. The hare is a source of food to the lynx, so with more lynx's...less hares... and less hares means either less food for the lynx and their population starts to die off...OR... The lynx adapt and start hunting new animals which could cause a massive disruption in the food chain.

Second question: When the number of hares increase in the environment it would mean more food for the lynx and other predatory animals. But with more food, comes more overpopulation. with plenty to eat the lynx population increases and that could cause problems for the environment, and other creatures.

What stage occurs between the 4 cell and 16 cell stage of development
finlep [7]
<span>The product of fertilization is a one-cell embryo with a diploid complement of chromosomes. Over the next few days, the mammalian embryo undergoes a series of cell divisions, ultimately leading to formation of a hollow sphere of cells known as a blastocyst. At some point between fertilization and blastocyst formation, the embryo moves out of the oviduct, into the lumen of the uterus.The images below demonstrate major transitions in structure during early embryogenesis in cattle. Note that in all of the the early stages, the embryo is encased in its zona pellucida. Embryos from other mammals have a very similar appearance, and the general sequence of stages is seen in all mammals.

Autism is a neurological disorder thought to be caused by mutant alleles of one or more genes. Scientists had been wondering why
Digiron [165]

Answer:

There is an accumulation of genetic mutations in the DNA of sperms due to its constant mitosis.

Explanation:

The germinative cells that will become sperms are under constant mitosis. During this process, DNA mutations can happen and be transmitted from one generation of cells to the other as the years go by, and more cell divisions take place, more mutations the DNA in the sperm will have. When the number of mutations reaches a certain level, his child will express these mutations and have autism.

The egg of the mother is not a factor because the germinative cells in women are not under constant mitosis, so there is not an accumulation of gene mutations. Women are born with an exact number of eggs for all their life.

Samuel has a block of modeling clay, three heavy blocks, and a hot plate covered by a tray as shown. How could he use these item
Olegator [25]

Answer:

Block of modeling clay is placed under three heavy blocks, and a hot plate covered by a tray.

Explanation:

Block of modeling clay is placed under three heavy blocks, and a hot plate covered by a tray is used for forming a metamorphic rock. Metamorphic rocks are formed when the rocks are placed to high heat, high pressure, hot mineral-rich fluids or combination of all these three factors. Conditions like these are found deep within the Earth so by placing block of modeling clay is placed under three heavy blocks, and a hot plate covered by a tray formed metamorphic rock.
