Answer: The probability of having an offspring that is dwarf in size is zero.
Explanation: Since tall phenotype is dominant to dwarf phenotype, let T represent allele for tall and t represent allele for dwarf. A heterozygous pea plant will have Tt genotype while a homozygous tall pea plant will have a TT genotype. A cross between them will produce two homozygous tall pea plants (TT) and two heterozygous tall pea plant (Tt). They will not have any offspring having a dwarf size. Therefore, the probability of having a dwarf offspring is zero.

Metal contain free electrons which makes it easier to transfer energy through the solid (conduction). Non-metals are poor conductors (insulators) because they do not contain free electrons.

Isotopes are atoms of the same element with the same atomic number but different mass number. unstable atoms atoms undergoes radioactive decay. Therefore radioactive decay is the process by which unstable nucleus loss energy by emitting radiations such as beta , alpha and gamma particles.
The initial mass of radium-226 is 6 grams and the new mass is 0.375 grams therefore the number of half lives undergone are 0.375 = 6× (1/2)n where n is the number of half lives. (1/2) n = 1/16
therefore n= 4. Meaning the isotope radium-226 has undergone 4 half lives
1 Half life = 1600 years
4 half lives = 1600 years × 4 = 6400 years
therefore, the rock reached its closure temperature 6400 years ago and secondly when the rock was discovered it had 5.625 g mass of radon-222.
Answer:
The correct answer is - pine, maple, elm and many more are conifer plants.
Explanation:
Conifers are the plant is that is cone bear nonvascular trees. These are the plants with woody trees except a few shrubs. These plants are described as the plants with leaves that appear to be needle-like and thin with a cone that bears seeds.
In the conifer plants, there are many trees including pine, maple, elm, firs, junipers, cedars, spruce and many more. These plants lack vascular tissues however they bear seeds in cones.
Thus, the correct answer is - pine, maple, elm and many more are conifer plants.
Answer:
Different temperatures in her backyard
Explanation:
The independent variable would be <u>the different temperatures in Pinky's backyard.</u>
The independent variable is a variable whose value is not affected by another variable during research. It is a variable that directly affects the actual variable that is measured - the dependent variable. The independent variable is usually varied in order to see the kind of effect it will produce on the dependent variable.
<em>In the case of Pinky, the different temperature at the backyard affects the number of cricket chirps. Hence, the temperature is considered the independent variable while the number of cricket chirp is considered the dependent variable.</em>
