Answer:
thamalus
Explanation:
Based on studies conducted by various neurologists, it can be said that in this situation that information was most likely first routed to the thamalus. This is a part of the brain that relays motor and sensory information to the cerebral cortex. It is also responsible for regulating sleep, consciousness and even alertness. Which is what was triggered (alertness) when you saw the spider crawling up your leg.
Answer:
E. A, B, and C are correct answers.
Explanation:
A male reproductive system is an organ system that produces sperm also called the male gamete. the male organ consists of two main structures which are penis and scrotum.
A female reproductive system is an organ that produces female gametes. it is a place where the male drops their sperm for fertilization during sexual reproduction.
a very A major difference between the human male and female reproductive tracts is the
- Temperature at which gamete production occur
- the location of the gonads
- also the fact that the scrotum houses testes and the ovaries are covered by protective capsule.
That is why i chose E because A, B and C are the correct answer.
Answer:
Operons afford the organism the opportunity to simultaneously regulate transcription of multiple genes, whose products are active in the same process.
Explanation:
Operon is the group of related genes and the operator and promoter sequences that regulate their expression. All the genes in an operon are expressed together and are under the regulation of the same promoter and operator sequences.
Operons consist of the genes that are involved in related metabolic pathways. For example, the genes that code for the enzymes of lactose catabolism are expressed together as lac operon. It allows simultaneous expression of the genes of lactose catabolism only when lactose is present in the medium. Similarly, these genes are inhibited simultaneously in absence of lactose by binding of repressor protein to the operator sequence.
Answer:
The correct answer would be - Having reliable access to food and being able to produce more calories per unit of land available led to population increase.
Explanation:
An increase in disease, sedentary agriculture, and increase in environmental degradation are three problem that is associated with the farming.
There are more benefits to continue agriculture is the ability of human kind to produce a food and access to plenty of food consistently which will led to increase the population.
Thus, the correct response would be - Having reliable access to food and being able to produce more calories per unit of land available led to population increase.
Answer:
D. A segment of DNA molecule
Explanation:
Gene is a segment of a DNA molecule that holds instruction needed for the synthesis of useful products (protein). Ideally, DNA is the storage material of genetic information in a cell. The DNA harbors the GENE, which itself is being expressed in order to use the information contained in it to produce useful products responsible for the phenotype of an organism.
A gene contains sequences made up of nucleotide bases that determines the sequence of amino acids to be produced, and ultimately the type of protein.
