Sweet yellow tomatoes with a pear shape bring a high price per basket to growers. Pear shape, yellow color, and terminal flower

position are recessive traits produced by alleles, f, r, and t, respectively.
The dominant phenotypes for each trait – full shape, red color, and axial flower position – are the product of dominant alleles F, R, and T. A farmer has two pure-breeding tomato lines. One is full, yellow, terminal and the other is pear, red, axial. Design a breeding experiment (crosses) that will produce a line with tomato that is pure-breeding for pear shape, yellow color, and axial flower position.

Answer and Explanation: The farmer has a pure-breeding line of tomato means the farmer has a tomato with genotype FFrrtt while the other line of tomato has genotype ffRRTT.

The cross between these lines gives a F1 generation of heterozygous full, red and axial or FfRrTt.

With an individual of F1 crosses with another individual of F1, the Punnet Square will be:

FfRrTt x FfRrTt

1) Dividing each characteristics, for simplicity:

          F         f

F       FF       Ff

f        Ff        ff

          R       r

R       RR     Rr

r        Rr      rr

         T      t

T       TT   Tt

t        Tt     tt

Analysing Punnett squares, we notice the line wanted (ffrrTT) will be produced, when an individual of F1 generation cross with another individual with the same generation.

The composition of the secretions of the eccrine glands is ________.metabolic wastes99% water, sodium chloride, trace amounts of
Gekata [30.6K]

Answer:

99% water, sodium chloride, trace amounts of wastes, and vitamin C

Explanation:

Eccrine glands are the main and major sweat glands of our body. These glands are found all over the skin but their density is higher on palm, soles, and head.  

99% of the secretion of the eccrine gland is water and in rest 1% it contains sodium, trace amounts of waste and a high amount of vitamin C is lost by the eccrine gland.  

As the eccrine gland is responsible for sweating so it helps in thermoregulation in the body. As 99% of secretion is water therefore dehydration and water loss is the major worry during excessive sweating.

Which is the first step that geologists must do to compare rock layers at distant locations? 1.find the absolute age of rocks at
VARVARA [1.3K]

Answer:

2.compare a layer at one location to layers at other locations

Explanation:

Comparing rock layers in distant places can be a challenge for geologists since these layers may have different environmental factors that caused different transformations in them.

Therefore, when it is necessary to establish a comparison between layers of rocks in different ligands, geologists must establish steps to make an efficient comparison and have results consistent with reality. To do this, they must first compare a layer in one location with layers in other locations, assign relative age to a layer in one location, and identify index fossils in one or more layers in one location.

If a 9.0-volt battery is placed across a 5.0-ohm resistance, the current will be _____ amperes.
irinina [24]
This is physics, electricity.
I'll break it down for you, very easy:
you have to use the formula V=IR
where V= voltage in volts (V)
I= current in Amperes (A)
R= resistance in ohms (Ω)

so what you require is I, current there you have to rearrange the formula to subject current;
I=V/R
=9/5= 1.8Ω (ans)

In anatomic position, the radius lies _____ to the ulna. inferior superior posterior medial lateral
kondor19780726 [428]

Answer: lateral

The radius is a long bone in the forearm. In anatomic position, it lies lateral to the ulna, which is smaller than the radius. Both radius and ulna connect to the humerus bone of the upper arm at the elbow joint. The radius pivots around the ulna to create movement at the proximal and distal radio-ulnar joints. Moreover, radius articulates in elbow joint, proximal radioulnar joint, wrist joint and distal radioulnar joint.

Calculate the rate of photosynthesis (mm/hr) for Elodea if when measuring net photosynthesis, the water level moved up 7mm from
ZanzabumX [31]

Answer:

With 6 we should multiply gross photosynthesis (as we were measuring gross photosynthesis for 10 min).

Explanation:

According to this question:-

Net photosynthesis- 3mm/20min- 1.5mm/10min

Cellular respiration- 1mm/15min- 0.66mm/10min

Gross photosynthesis = Net photosynthesis + Cellular respiration = 1.5+0.66 = 2.16 (mm/10min)

Rate of photosynthesis = (gross photosynthesis)6 = 2.16 *6 = 12.96 mm/hr

As we gage the photosynthesis rate in hr.
