(here's a starter bc i'm not good at these )i think we should be able to have our field trips because it gives the students the opportunity to learn new things, and engage in new activities. (then continue to talk about those topics and explain why they are good for students)

My principal is thinking about canceling all school field trips this year to save money but I honestly think they shouldn’t.Field trips are a fun way of teaching students factual things that they might need to know for the future if the kids get out of the classrooms and go on field trips they will learn better because students get bored in class and stop paying attention I think we can find a better way to save money like (and say what your school uses that you don’t really need) you should get an A or B depending on your teacher

Why does a<br> vestigial pelvis show that<br> the ancestors of the modern<br> whale once had legs?
OleMash [197]
The research party began by exploring the embryonic development of whales' cousins, the dolphins. These creatures are intriguing because, for a brief time during development, they sprout hind limbs . That's why dolphins lose their 'legs'.” In whales, however, the story is more complex.

Brown eye-color alleles are dominant over blue eye-color alleles, which are recessive. jenna has brown eyes. her husband, bill,
Vinil7 [7]
Brown eye-color is dominant while the blue-eye color is recessive. Therefore, the homozygous for brown color is BB and the homozygous for brown color is bb. Thus, the heterozygous will be Bb (brown color). Since James has blue colored eyes  a child of Jenna (brown color) and bill (blue color) then it means Jenna is heterozygous (Bb). Jenna is described  as being a carrier of the allele for blue eyes.

Under which conditions are the lac structural genes expressed most efficiently?
madam [21]

Lac genes are most effectively expressed in presence of Lactose and its analogs when glucose is absent.

Explanation:

A unit of prokaryotic gene expression and regulation,which includes structural genes and regulatory sequences recognized by regulatory gene product is called operon.

<em>Lac </em>structural genes are a part of<em> Lac</em> operon. The <em>Lac </em>operon consists of three, structural genes,an operator and a promoter.The product of Lac operon is involved in the conversion of disaccharide lactose into glucose and Galactose.

Lactose and its analogs are inducers of<em> Lac </em>operon. So, the structural genes are best expressed in presence of Lactose. Glucose and galactose are repressors of lac gene so the genes are repressed in presence of glucose.
