For each statement below, indicate if it is TRUE or FALSE and explain why. (a) All highly conserved stretches of DNA in the geno

me are transcribed into RNA. (b) To find functionally important regions of the genome, it is more useful to compare species whose last common ancestor lived 100 million years ago rather than 5 million years ago. (c) Most mutations and genome alterations have neutral consequences.

How are spring tides different from Neap Tides. Give at least 2 reasons _______
dybincka [34]

Answer:

Seven days after a spring tide, the sun and moon are at right angles to each other. This produces moderate tides known as neap tides, meaning that high tides are a little lower and low tides are a little higher than average. Neap tides occur during the first and third quarter moon, when the moon appears "half full.

Are there more producers or consumers in and ecosystem? Why?
Dafna1 [17]
<span>Producers or autotrophs

Autotrophs obtain energy by the process of photosynthesis. Any living organism need energy to survive and autotrophs are no different. Two types of autotrophs are present and they are Photoautotrophs and Chemoautotrophs. The Photoautotrophs rely on the energy produced during the process of photosynthesis and the Chemoautotrophs get their energy from most of the inorganic substances. Phtoautotrophs actually get their energy from the sunlight and then convert it into reusable form. In case of Chemoautotrophs ammonia is an important source of energy for them.</span>

Evolution of shorter legs in anole lizards placed on small, hurricane-scrubbed islands is an example of which type of evolution?
Paraphin [41]

This type of evolution is known as Microevolution.

Microevolution is the gradual shift in allele frequencies within a population.  Four separate processes—mutation, natural and artificial selection, gene flow, and genetic drift—are responsible for this shift. Compared to the changes referred to as macroevolution, this transformation occurs over a very brief period of time (in evolutionary terms).

The area of biology known as population genetics offers a mathematical framework for the study of the microevolutionary process. The goal of ecological genetics is to track microevolution in the natural world. Microevolution is frequently seen in visible forms of evolution, such as antibiotic-resistant bacterial strains.

Speciation, which supplies the building blocks for macroevolution, may result from microevolution.

Therefore, the correct answer is Microevolution. The Microevolution in which Anole lizards on tiny, hurricane-ravaged islands evolved shorter legs.

If a population doubles in the course of 100 years, its growth rate would be approximately ________%.
VladimirAG [237]

Answer:

The population increases at a rate of approx. 0.70% per year.

Explanation:

The population (P) as a function of time (t) is as follows:

P = P_0(1 + i)^t.

Given that the population doubles in 100 years, let's calculate i:

2P_0 = P_0(1+i)^{100}\\\\(1+i)^{100} = 2\\\\1 + i = 2^{\frac{1}{100}}\\\\1 + i = 1.0069556\\\\i = 0.0069556≅      0.70%
