As scientists began investigating living things and their cellular structure they developed a set of principles that are now kno

wn as the cell theory
The statements below summarize cell theory
• All living things are made up of cells.
Cells are the basic units of structure and function in living things
• New cells are produced from existing cells.
Daniel proposes that if scientists continue to gather evidence in support of the cell theory, they eventually should reclassify the theory as a law of
cells. Which statement is the most useful evaluation of Daniel's proposal?

A The proposal is reasonable, because theories often are reclassified as laws when the evidence is overwhelming

B. The proposal is reasonable, although only rarely is enough evidence gathered to reclassify theories as laws

C.The proposal is not reasonable because scientists have discovered too many exceptions to the cell theory to state it as a law.

D. The proposal is not reasonable, because a theory is never reclassified as a law, nor is a law reclassified as a theory,

vagabundo [1.1K]

Answer:

P (actually that randomly selected person has diabetes given as given by the lab) = 0.7725

Explanation:

A probability is a number, between 0 and 1, expressing the precise likelihood of an event happening.

Probability (person actually has diabetes) = 5.9%

P(lab test says that they have diabetes) = 0.0764

P (actually that randomly selected person has diabetes given as given by the lab) = 0.7725

Workings shown in the figure below.

The ________ extends through the hindbrain, midbrain, and forebrain.
Lemur [1.5K]

Answer: option C) Pons

Explanation:

Pons, or better still, the pons Varolii is a band of nerve fibers located within the brain stem. While, the brain stem is known to connect the spinal cord(Hind brain) to the fore brain

Thus, Pons extends through the hindbrain, midbrain, and forebrain.

active transport occurs in cells for example when Na-k pump is at work.Any process that involves active transport most often inv
vekshin1

Answer:

Any process that involves active transport most often involves the​ expenditure of energy in the form of ATP hydrolysis.

Explanation:

Active transport in cells is a form of transport which involves the transport of solute molecules across a membrane against a concentration gradient using energy provided from some chemical reaction occuring in the cell.

Active transport is an endergonic (energy-requiring) process and therefore, must proceed only when coupled to an exergonic (energy-releasing) process such as the breakdown of ATP, an oxidation reaction, absorption of sunlight, etc.

In many instances in cell, such as the Na/K pump, ATP hydrolysis is the the common exergonic reaction to which active transport is coupled to.

Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offsprin
Andrei [34K]

Answer:

The correct answer would be 2 in 4.

According to the question Xo and XO show codominance and express themselves completely when present in heterozygous condition. Cats bearing XoXO show patchwork of black and orange fur and are called tortoiseshell cats.

Xo codes for orange color fur and XO codes for black color fur. In addition, Y chromosome does not contain any gene associated with fur color.

Now, genotype of mother cat is XOXO (orange fur). So, the gametes formed would be XO only.

The genotype of father cat is XoY(black fur). So, the gametes would be Xo and Y.

The cross would lead to the formation of two male cats each having XOY as their genotype and two female cats each with XOXo as their genotype.

Hence, both the male cats would show orange fur and both the female cats would show patchwork of orange and black fur.

Therefore, we can conclude that 2 out of 4 would exhibit tortoiseshell coloring.
