Features of monocot and dicot plants. Images from Purves et al., Life: The Science of Biology, 4th Edition, by Sinauer Associates (www.sinauer.com) and WH Freeman (www.whfreeman.com), used with permission.
Monocot seeds have one "seed leaf" termed a cotyledon (in fact monocot is a shortening of monocotyledon). Dicots have two cotyledons. Both groups, however, have the same basic architecture of nodes, internodes, etc.

2) autosomal dominant
3)Sex linked
4) both 1 and 2
Answer:
1
Explanation:
it's an autosomal recessive trait.
Answer:
3) sex-linked
Explanation:
It is carried by the sex chromosomes, mainly the X chromosome. An individual has the disease when he gets an X chromosome bearing the disease from a carrier or infected mother or both two X chromosomes each bearing the disease, one from each parent. Thus in the case of a girl... Hence, it is sex-linked

Your bone cells and heart cells contain the exact same DNA but have very different functions. Explain how this i so.
Answer:
This is so because of GENE EXPRESSION
Please find the explanation below
Explanation:
All living cells including the bone cells and heart cells described in this question are made up of genetic material known as DNA. However, cells of the same organisms contain the exact same DNA, but they perform different functions due to GENE EXPRESSION.
The bone cells and heart cells for example perform different functions because certain genes in the bone cells are expressed while others are inhibited from being expressed. The same goes for the genes in heart cells. In other words, genes are not expressed at the same time, hence, leading to different functions or specialization of cells called CELL DIFFERENTIATION.

In order to lose weight, energy expenditure must exceed energy intake. Negative energy balance occurs when the body is using more energy than it is taking in BMR or basal metabolic rate, is the main component of energy expenditure. This is the number of calories we burn that is needed for basic bodily functions, like pumping blood through our veins entyme production, cell turnover, and breathing but does not Include digestion. A BMR for an average, healthy adult is between 1200 calorles and 1800 calories per day, in order to lose 1 b of weight a negative balance of 3500 calories must occur Arthur is a 20-year-old student who gained 12 lb since becoming a college student 2 years ago for the past 6 months, his welght has stabilized. Now he is interested in losing those 12 lb in 2 months. Arthur consumes 3000 calorles per day. In order to lose 12 lb in 8 weeks, Arthur will need to a. eat 2750 calorles per day and exercise enough to burn 500 calories per day b. consume 3500 alories per day and exercise enough to bum 500 calorles per day c. Geat 3000 calories of low-fat food per day and exercihe seven times per week, buning 100 calories each time d. run 6 miles per day, buming 800 calories, and eat 2500 calories of a high protein diet per day
Answer:
a. eat 2750 calories per day and exercise enough to burn 500 calories per day
Explanation:
To lose 1 lb of weight= - 3500 cal
Arthur consumes 3000 calories per day
To lose 12 lb in 8 weeks (56 days) = - 3500 cal x 12 lb = - 42,000 cal
Calorie consumption and burn off per day = 2750 cal - 500 cal = 2250 cal
Arthur's consumption = Daily normal calorie intake - Daily calorie intake for diet >>
3000 cal - 2250 cal = 750 cal per day >> 750 cal x 56 days = 42,000 cal
describe the factors that determine female fitness?
Answer: Maintaining a good level of physical fitness is something that we should all aspire to do. But it can be difficult to determine what fitness entails. According to the United States Department of Health and Human Services, physical fitness is defined as “a set of attributes that people have or achieve that relates to the ability to perform physical activity.”This description goes beyond being able to run fast or lift heavy weights. Despite being important, these attributes only address single areas of fitness. This article provides details of the five main components of physical fitness.

What uses bacteria to copy DNA?
O A. Nuclear transfer
O B. Gel electrophoresis
O C. Recombinant DNA technology
O D. Polymerase chain reaction
Answer:
C.
Explanation:
The method that uses bacteria to copy DNA is recombinant DNA Technology. To copy the DNA, the recombinant DNA method uses bacteria such as E. Coli whose plasmids are combined with various gene to produce the substance that is wanted.
Polymerase chain reaction uses bacteria to copy DNA.Therefore, the correct option is D.
What is polymerase chain reaction?Polymerase Chain Reaction is a laboratory technique used to amplify a specific DNA sequence, making many copies of it. The process involves repeated cycles of heating and cooling a reaction mixture containing the DNA template, primers, and a heat-stable DNA polymerase enzyme.
The DNA polymerase enzyme used in PCR is derived from a bacterium called Thermus aquaticus, which can withstand the high temperatures used in the reaction. By copying the DNA sequence multiple times, PCR enables researchers to study and analyze small amounts of DNA, such as those obtained from crime scenes or ancient fossils.Therefore, the correct option is D.
