D. develop technology and resources capable of sending the general population into space on a regular basis
Answer:
D
Explanation:
Develop technology and resources capable of sending the general population into space on a regular basis.
What is Developmental Technology?L. Mumford presented an intriguing theory regarding the origin of technology, contending that biotechnology gave rise to both machine and gun technology.
Technique is derived from the characteristics of how people behave and, in its earliest forms, is directly tied to the origin of man. It was first and foremost life-focused, and only afterwards was it work-focused.
According to L. Mumford, technique with a focus on power and output developed much later. He held that the impersonal aspects of human adaptability to the outside world are what give origin to technology.
Therefore, Develop technology and resources capable of sending the general population into space on a regular basis.

surroundings? Explain.
pls help me. i beg you
Answer:
The pollinators help spread the pollen of the flowering plants to help them reproduce. If the flowering plants blended into their surroundings, the pollinators would not be able to identify the flowering plants, and the plants would eventually die off or become extinct.

4. A woman with defective tooth enamel (autosomal recessive) and normal color vision, (X-linked) who had a color blind father with normal tooth enamel and a mother with normal vision and defective tooth enamel, marries a color blind first cousin with normal tooth enamel who had a father with defective tooth enamel. What is the probability of their having a child with normal tooth enamel and color blindness
Answer:
The probability of their having a child with normal tooth enamel and color blindness is 3/8 or 0.375
Explanation:
Let the alleles for normal and defective tooth enamel be T and t respectively.
Color blindness is on the X-Chromosome. Let the allele normal vision and colour blindness be Xn and Xc respectively.
The woman had a colour blind father (XcY) and a normal vision mother, so her allelic pair for vision will be XnXc.
Her father had normal tooth enamel while her mother had a defective tooth enamel, therefore, she will have the allelic pair, Tt.
Her genotype for vision and tooth enamel will be XnXcTt.
Her husband who is color blind with normal tooth enamel had a father with defective tooth enamel, tt. Therefore, her husband's genotype for vision and tooth enamel will be XcYTt.
From the dihybrid cross of XnXcTt and XcYTt, the following offspring are obtained:
XnXcTT, XnXcTt, XnYTT, XnYTt
XnXcTt, XnXctt, XnYTt, XnYtt
XcXcTT, XcXcTt, XcYTT, XcYTt
XcXcTt, XcXctt, XcYTt, XcYtt
From the results of the cross, a child with normal tooth enamel and color blindness will have the following genotypes: XcXcTT, XcXcTt, XcYTT, XcYTt, XcXcTt, XcYTt.
Probability of their having a child with normal tooth enamel and color blindness = 6/16 = 3/8 or 0.375

Explanation:

Purple: FF /White: ff the principles of dominance and segregation to analyze the diagram, alleles would you expect in the F1 plants. Thus, option (a) is correct.
What is segregation?The Segregation Principle defines how pairs of gene variations are divided into reproductive cells. Gregor Mendel discovered the segregation of gene variants, known as alleles, and their accompanying qualities in 1865. During meiosis, allele pairs (different features of the same gene) are separated so that they can pass to distinct gametes.
The diagram was analyzed using the principles of supremacy and segregation. The principle of the impact in segregation was described as Purple: FF / White: ff. This inheritance pattern is known as partial dominance, which means that neither allele is completely dominant over the other: both genotypes can be seen at the same time.
As a result, the Purple: FF /White: ff the principles of dominance and segregation.

Which statement below would best illustrate the concept of natural selection?
A an organism can return to the characteristics of its ancestors
B a population of animals will move from one region to another
those organisms that are best adapted to the environment will survive to produce more offspring
D all organisms are made up of cells
Answer:
C. those organisms that are best adapted to the environment will survive to produce more offspring
Explanation:
Natural selection is a key concept in the formulation of the theory proposed by Darwin in 1859. Natural selection is defined as the main force that drives the prevalence and the increase of advantageous phenotypic traits. Selection natural acts by differential survival and reproduction of individual organisms that have better adapted to the environmental conditions in which these organisms live. These organisms with a greater adaptive fitness have more chances to survive and reproduce, thereby transmitting (and perpetuating) their genes to the following generations.
Answer:
those organisms that are best adapted to the environment will survive to produce more offspring
Explanation:
those organisms that are best adapted to the environment will survive to produce more offspring

natural selection vs artificial
Answer:
Please read the explenation for I must go into detail to explain this.
Explanation:
So before I answer your question, I am going to explain what the two things are.
Natural selection:
Natural selection is the evolution of traits in a species due to changes in genetics that is mainly caused by enviormental problems and changes.
If this is a bit confusing, here is an example:
Lets say that a Mandarin beatroot lizard is being killed off by the Mandarin carrot bird because all the trees in the area have turned yellow. 100 years from the time this happened, the Mandarin beatroot lizard that's population was 85% red and 15% yellow is now 90% yellow and only 10% red.
This is because of natural selection. THe Mandarin carrot bird was killing a large portion of the red population. The yellow population was killed only occasionaly. When the Madarin beatroot lizard went to breed, there were more yellow lizards breeding than red lizards. If you know how genetics work, then you know that in simple terms, this means more lizards will be yellow in the next genetration.
Slowl;y as the generations passed, more and more yellow lizards were bred and born. 100 years later, over generations and generations, the population was almost coimpeltly yellow.
Artifical selection:
Artifical selection is where the human race selects a species and bred specific organisms of that species so that the specific trait being bred for is more evident in the species.
Again, if this is confusing, here is an example:
The lab NV-110 was taking bearlybubble wolves with shorter noses and breeding them together. After 30 years, and many generations, the bearlybubble wolves had noses that were half a inch shorter than the orginal bearlybubble wolves. When the new wolves were let into the forest they had been taken from, half of the died in the first week due to starvation.
The humans took specific traits in a species and bred them together, this process was repeated over 30 years. The specific trait of the new generation of orgniasms has been changed, but this change affected the orgnaisms survive, and was dentrimental to the species.
So now knowing the two things, what do you think the difference is? Think about ti for a minute before reading more.
The difference betweent the two types of selection is:
Artifical selection can harm or possibly nuetral for the organism, wheareas natural selection will be helpful or nuteral to the organism.Artifical selection involves humans, wheareas naturals election does not,Artifical selection does not need any specific change in the enviorment or world to happen, wheareas natural selection does.Artifical selection is usally quicker than natural selction for artificial selection is purposful breeding, whereas natural selection is by-chance breeding.I hope this make sense to you, I can try to make this simpler or more detailed if you want me to. ;)
