Answers

Answer 1

Answer:

Answer 2

Answer:

The ventral side is lighter than the dorsal side and more pale and kind of flattened unlike the dorsal side which is darker and round.

Why is it important to monitor the pH and other factors in the AgWorks lab

Answers

Answer:

To know the actual pH for a particular organism.

Explanation:

It should be understood that in a 6,100-square-foot lab and classroom named AgWorks, students not only learn how to grow food in a controlled environment, but also explore and have the idea of agriculture-related careers.

In this aspect, the monitoring of pH is very important because not all organism survive in acidic and basic mediums, but there are some that required neutral medium for their survival. And this is the reason why to always affirm the particular pH necessary for the survival of a particular organism.

Why xylem and phloem are called complex tissues? How are they different from one another?

Answers

Answer:

Xylem and phloem are called complex tissues because they are made up of more than one type of cell working together as a unit. The xylem transports H2O and minerals upward from the roots to the leaves, and is composed of tracheid cells which are dead at maturity (no active nucleus, makes the tree stem hard). If plants don't have xylem, they will stay lower to the ground as it is responsible for making the tree grow upward. The ends of the xylem tubes are tapered (pointed), materials are passed along one cell at a time, and the tubes are narrow and continuous. The phloem transports sugars and proteins downward from the leaves to the stems and storage roots. The cells that make up the phloem are called sieve tubules and companion cells. The companion cells have the nucleus and the sieve tubules contain the cytoplasm.

Explanation:

My teacher helped us remember using the phrase "phloem down the river" because it sounds like 'flowing down the river' (to help remember that phloem transports downward and xylem transports upward.)

It decreased in frequency over time.

It became extinct.

It is carried on a recessive allele.

Answers

It decreased in frequency over time.

Trait B decreased in frequency over time. So, the correct option is A.

What is trait?

A trait is an attribute or characteristic of an organism that is influenced by its genes, according to genetics. Behavioural and physical characteristics, including intelligence and friendliness, can be altered by a combination of hereditary and environmental variables.

A trait is a distinctive quality or attribute that can be acquired by environmental circumstances, genetic inheritance, or both. In biology, traits are observable and quantifiable qualities of an organism, including its physical characteristics, behaviour, and other traits. For instance, physical characteristics like eye colour, height, and hair texture can all be passed on through genetics.

Hence, the correct option is A.

organisms. Describe one example of this kind of activity.

Answers

Answer:

Deforestation is one major human activity that harms both people and organisms. Cutting down trees lowers Earths ability to create fresh air, which leads to more toxic and polluted areas that can cause problems with breathing and even lead to lung cancer. Deforestation can harm other organisms because many animals such as birds, squirrels, and owls, look to the trees for a habitat. However, as we destroy they can cause a decrease in population which leads to an even bigger problem in the food chain.

Jason joined a group that would work towards solving the workplace safety issues in his organization. Arrange Jason’s actions according to the stages of development of his group.

Answers

Answer:

- Jason asked his fellow group members  about their hobbies and interests .

- Jason and another member disagree on  what their respective roles should be in  the group.

- Jason resolved his differences with the  other group members .

- Jason began working with the group  members as a complete unit .

Explanation:

The correct order of Jason's actions in the stages of the development of his group would be as mentioned above. After the first step of the formation of the group, the next step is 'storming' in which the ideas are generated. Thus, Jason asks the group members regarding their interests and hobbies as it assists in the generation of effective ideas for problem-solving. The next step would be 'norming' in which the conflicts would arise due to disagreement regarding the respective roles of group members. Then, Jason as a team member would resolve the differences among the team members to reach a common solution. After everyone agrees upon the same idea, Jason can pursue working with the group as a complete unit. These stages are crucial for the effective development of the group and achieve desired results through cooperation and teamwork.

Shrinkage at Walmart In 2015, the worlds largest retailer, Walmart, announced a quarterly increase in sales that was accompanied by an increase in expenses that reduced its hoped-for profit. In discussing the higher expenses, the company mentioned "shrinkage" three times in its written press release and 13 times in its conference call with financial analysts. The company attributed a significant part of its increased shrinkage to shoplifting and outright theft, including one instance in which a team of thieves pushed a shopping cart full of electronics out a back door and loaded them into a waiting car. To combat these problems, which are unfortunately common in retailing, the company announced it was restarting a training program for employees that helps them learn how to spot shoplifters and fellow employees who are pilfering, along with adding staff to areas of the store that contain high-value or easy-to-steal items. They also plan to start checking customers receipts at store exits. In addition to these measures, however, the company also reported that a sizable portion of the shrinkage results from difficulties encountered in managing inventory flow throughout the companys distribution network and its stores. When warehouses and store backrooms become overstocked with inventory, it can be difficult to determine which items should be discounted and moved to the stores shelves. In recent years, Walmart has increased its sales of grocery and food items, which can be damaged more easily than its other inventory and for which failure to monitor expiration dates can be costly. To deal with these backroom inventory management issues, the company has added employees to staff those areas. Walmarts U.S. supply chain includes more than 100 distribution centers from which the company makes deliveries to its more than 5000 stores and Sams Club locations using its fleet of more than 6000 trucks. Managing the flow of inventory from the companys suppliers through its distribution centers and into its retail outlets is a mammoth task and, as discussed in this chapter, the company has made attempts to use technology in new and creative ways to address these challenges in the past. REQUIRED Q1) Become familiar with RFID technology and its potential uses in Walmarts supply chain using the information presented in this chapter and information you obtain through the Web Links, your favorite search engine, and your library.
