Answer:
<em>C: Purple and long</em>
Explanation:
- Let <em>R</em> represents flower color. <em>RR </em>genotype will give red flower, <em>Rr</em> will be purple (incomplete dominance) and <em>rr </em>will be white.
- Let <em>L</em> represents radish's length. <em>LL</em> and <em>Ll</em> will give long radishes since long radish allele is dominant over oval radish allele.<em> ll</em> genotype will be result in oval shape radishes.
Crossing <em>RRLL</em> with<em> rrll:</em>
All the progeny will have RrLl genotype (see the attached image for Punnet's square result).
Phenotypically, they will appear with purple colour flower and long radishes.
The correct answer is C.
Answer:
The statement is true.
Explanation:
The question is incomplete, here is the full question:
Many fad treatments for autism spectrum disorders make the parents feel good that they are trying something, but otherwise, they are a waste of time and money.
Is the statement true or false?
The given statement above is true because there are currently no known treatments or medicines discovered to treat Autism Spectrum Disorder (ASD) and most of the things the patients get recommended are only able to help with basic symptoms such as seizures or allergies etc. so the statement that they are a waste of time and money can be considered true.
I hope this answer helps.
<h2>The given statement is true</h2>
Explanation:
The recent finding of the fossils which showed that <em>Homo erectus</em> and <em>Homo habilis</em> lived side by side in eastern Africa for perhaps half a million years challenged the conventional way that these two species evolved one after the other(<em>H.habilis</em> 1.44 million years old and <em>H.erectus </em>1.55 million years old)
- The fossils were found in Kenya and took years to prepare the specimens for study and to be sure of the identification of the species, the scientists said
- University of Utah geologists determined the dates of the fossils from volcanic ash deposits
- The most recent <em>Homo habilis</em> that had been known was about the same age as the earliest <em>Homo erectus</em><em>,</em> said Daniel Lieberman, a professor of biological anthropology at Harvard University, “Now we have extended the duration of the habilis species, and there’s no doubt that it overlaps considerably with erectus”
- The fact that the two hominid species lived together in the same lake basin for so long and remained separate species, Meave Leakey said in a statement from Nairobi, “suggests that they had their own ecological niche, thus avoiding direct competition”
The "control" step of intergrated pest management involves the use of pesticides to control pests and their damage.
<u>Explanation:</u>
IPM have four steps, which is a sequence of pest control method. When the thresholds for surveillance, detection and intervention suggest the need for pest control and prevention measures are no longer efficient or usable, then IPM (intergrated pest management) initiatives determine the appropriate management system for both efficacy and risk.
Efficient, less dangerous pest controls, involving highly concentrated chemicals like pheromones to hinder pest mating or mechanical control like trapping or weeding, are selected first. If more analysis, detection and intervention thresholds suggest that less dangerous controls do not operate, then alternative pest control approaches, like targeted pesticide spraying, will be implemented.
